- * Method:
- *	1. Argument Reduction: given the input x, find r and integer k such
- *	   that
- *	                   x = k*ln2 + r,  |r| <= 0.5*ln2 .
- *	   r will be represented as r := z+c for better accuracy.
- *
- *	2. Compute exp(r) by
- *
- *		exp(r) = 1 + r + r*R1/(2-R1),
- *	   where
- *		R1 = x - x^2*(p1+x^2*(p2+x^2*(p3+x^2*(p4+p5*x^2)))).
- *
- *	3. exp(x) = 2^k * exp(r) .
- *
- * Special cases:
- *	exp(INF) is INF, exp(NaN) is NaN;
- *	exp(-INF)=  0;
- *	for finite argument, only exp(0)=1 is exact.
- *
- * Accuracy:
- *	exp(x) returns the exponential of x nearly rounded. In a test run
- *	with 1,156,000 random arguments on a VAX, the maximum observed
- *	error was 0.869 ulps (units in the last place).

- *	Logarithm in IEEE Floating-Point arithmetic." ACM Trans.
- *	Math Software, vol 16. no 4, pp 378-400, Dec 1990).
- *
- * Calculates log(2^m*F*(1+f/F)), |f/j| <= 1/256,
- * where F = j/128 for j an integer in [0, 128].
- *
- * log(2^m) = log2_hi*m + log2_tail*m
- * since m is an integer, the dominant term is exact.
- * m has at most 10 digits (for subnormal numbers),
- * and log2_hi has 11 trailing zero bits.
- *
- * log(F) = logF_hi[j] + logF_lo[j] is in tabular form in log_table.h
- * logF_hi[] + 512 is exact.
- *
- * log(1+f/F) = 2*f/(2*F + f) + 1/12 * (2*f/(2*F + f))**3 + ...
- * the leading term is calculated to extra precision in two
- * parts, the larger of which adds exactly to the dominant
- * m and F terms.
- * There are two cases:
- *	1. when m, j are non-zero (m | j), use absolute
- *	   precision for the leading term.
- *	2. when m = j = 0, |1-x| < 1/256, and log(x) ~= (x-1).
- *	   In this case, use a relative precision of 24 bits.
- * (This is done differently in the original paper)

- *	0	return signalling -Inf
- *	neg	return signalling NaN

-.Ft double
-.Fn atan2 "double y" "double x"
-.Ft float
-.Fn atan2f "float y" "float x"
-.Sh DESCRIPTION
-The
-.Fn atan2
-and the
-.Fn atan2f
-functions compute the principal value of the arc tangent of
-.Fa y/ Ns Ar x ,
-using the signs of both arguments to determine the quadrant of
-the return value.
-.Sh RETURN VALUES
-The

-in the range

-if x = y = 0, or
-.It Ta
-.Pf sign( Ar y Ns )*\\*(Pi/2 Ta
-if
-.Ar x
-= 0 \(!=
-.Ar y .
-.El
-.Sh NOTES
-The function
-.Fn atan2
-defines "if x > 0,"
-.Fn atan2 0 0
-= 0 despite that previously
-.Fn atan2 0 0
-may have generated an error message.
-The reasons for assigning a value to
-.Fn atan2 0 0
-are these:
-.Bl -enum -offset indent
-.It
-Programs that test arguments to avoid computing
-.Fn atan2 0 0
-must be indifferent to its value.
-Programs that require it to be invalid are vulnerable
-to diverse reactions to that invalidity on diverse computer systems.
-.It
-The
-.Fn atan2
-function is used mostly to convert from rectangular (x,y)
-to polar
-.if n\
-(r,theta)
-.if t\
-(r,\(*h)
-coordinates that must satisfy x =
-.if n\
-r\(**cos theta
-.if t\
-r\(**cos\(*h
-and y =
-.if n\
-r\(**sin theta.
-.if t\
-r\(**sin\(*h.
-These equations are satisfied when (x=0,y=0)
-is mapped to
-.if n \
-(r=0,theta=0).
-.if t \
-(r=0,\(*h=0).
-In general, conversions to polar coordinates
-should be computed thus:
-.Bd -unfilled -offset indent
-.if n \{\
-r	:= hypot(x,y);  ... := sqrt(x\(**x+y\(**y)
-theta	:= atan2(y,x).
-.\}
-.if t \{\
-r	:= hypot(x,y);  ... := \(sr(x\u\s82\s10\d+y\u\s82\s10\d)
-\(*h	:= atan2(y,x).
-.\}
-.Ed
-.It
-The foregoing formulas need not be altered to cope in a
-reasonable way with signed zeros and infinities
-on a machine that conforms to
-.Tn IEEE 754 ;
-the versions of
-.Xr hypot 3
-and
-.Fn atan2
-provided for
-such a machine are designed to handle all cases.
-That is why
-.Fn atan2 \(+-0 \-0
-= \(+-\*(Pi
-for instance.
-In general the formulas above are equivalent to these:
-.Bd -unfilled -offset indent
-.if n \
-r := sqrt(x\(**x+y\(**y); if r = 0 then x := copysign(1,x);
-.if t \
-r := \(sr(x\(**x+y\(**y);\0\0if r = 0 then x := copysign(1,x);

-These functions will return the appropriate computation unless an error

-The functions
-.Fn pow x y
-and
-.Fn powf x y
-raise an invalid exception and return an \*(Na if
-.Fa x
-< 0 and

-is not an integer.
-An attempt to take the logarithm of \*(Pm0 will result in

-An attempt to take the logarithm of a negative number will
-result in an invalid exception, and an \*(Na will be generated.
-.Sh NOTES
-The functions exp(x)\-1 and log(1+x) are called
-expm1 and logp1 in
-.Tn BASIC
-on the Hewlett\-Packard
-.Tn HP Ns \-71B
-and
-.Tn APPLE
-Macintosh,
-.Tn EXP1
-and
-.Tn LN1
-in Pascal, exp1 and log1 in C
-on
-.Tn APPLE
-Macintoshes, where they have been provided to make
-sure financial calculations of ((1+x)**n\-1)/x, namely
-expm1(n\(**log1p(x))/x, will be accurate when x is tiny.
-They also provide accurate inverse hyperbolic functions.
-.Pp
-The function
-.Fn pow x 0
-returns x**0 = 1 for all x including x = 0, \*(If, and \*(Na .
-Previous implementations of pow may
-have defined x**0 to be undefined in some or all of these
-cases.
-Here are reasons for returning x**0 = 1 always:
-.Bl -enum -width indent
-.It
-Any program that already tests whether x is zero (or
-infinite or \*(Na) before computing x**0 cannot care
-whether 0**0 = 1 or not.
-Any program that depends
-upon 0**0 to be invalid is dubious anyway since that
-expression's meaning and, if invalid, its consequences
-vary from one computer system to another.
-.It
-Some Algebra texts (e.g.\& Sigler's) define x**0 = 1 for
-all x, including x = 0.
-This is compatible with the convention that accepts a[0]
-as the value of polynomial
-.Bd -literal -offset indent
-p(x) = a[0]\(**x**0 + a[1]\(**x**1 + a[2]\(**x**2 +...+ a[n]\(**x**n
-.Ed
-.Pp
-at x = 0 rather than reject a[0]\(**0**0 as invalid.
-.It
-Analysts will accept 0**0 = 1 despite that x**y can
-approach anything or nothing as x and y approach 0
-independently.
-The reason for setting 0**0 = 1 anyway is this:
-.Bd -ragged -offset indent
-If x(z) and y(z) are
-.Em any
-functions analytic (expandable
-in power series) in z around z = 0, and if there
-x(0) = y(0) = 0, then x(z)**y(z) \(-> 1 as z \(-> 0.
-.Ed
-.It
-If 0**0 = 1, then
-\*(If**0 = 1/0**0 = 1 too; and
-then \*(Na**0 = 1 too because x**0 = 1 for all finite
-and infinite x, i.e., independently of x.

-.Sh DESCRIPTION
-The
-.Fn feclearexcept
-routine clears the floating-point exception flags specified by
-.Fa excepts ,
-whereas
-.Fn feraiseexcept
-raises the specified exceptions.
-Raising an exception causes the corresponding flag to be set,
-and a
-.Dv SIGFPE
-is delivered to the process if the exception is unmasked.
-.Pp
-The

-function determines which flags are currently set, of those specified by

-.Pp
-The
-.Fn fegetexceptflag
-function stores the state of the exception flags specified in

-in the opaque object pointed to by
-.Fa flagp .
-Similarly,
-.Fn fesetexceptflag
-changes the specified exception flags to reflect the state stored in
-the object pointed to by

-Note that the flags restored with

-must be a (not necessarily proper) subset of the flags recorded by

-.Pp
-For all of these functions, the possible types of exceptions
-include those described in
-.Xr fenv 3 .
-Some architectures may define other types of floating-point exceptions.
-.Sh IMPLEMENTATION NOTES
-On some architectures, raising an overflow or underflow exception
-also causes an inexact exception to be raised.
-In these cases, the overflow or underflow will be raised first.
-.Pp
-The
-.Fn fegetexceptflag
-and
-.Fn fesetexceptflag
-routines are preferred to
-.Fn fetestexcept
-and
-.Fn feraiseexcept ,
-respectively, for saving and restoring exception flags.
-The latter do not re-raise exceptions and may preserve
-architecture-specific information such as addresses where
-exceptions occurred.
-.Sh RETURN VALUES
-The
-.Fn feclearexcept ,
-.Fn fegetexceptflag ,
-.Fn feraiseexcept ,
-and
-.Fn fesetexceptflag
-functions return 0 upon success, and non-zero otherwise.

-.Sh DESCRIPTION
-The
-.In fenv.h
-routines manipulate the floating-point environment,
-which includes the exception flags and rounding modes defined in
-.St -ieee754 .
-.Ss Exceptions
-Exception flags are set as side-effects of floating-point arithmetic
-operations and math library routines, and they remain set until
-explicitly cleared.
-The following macros expand to bit flags of type
-.Vt int
-representing the five standard floating-point exceptions.
-.Bl -tag -width ".Dv FE_DIVBYZERO"
-.It Dv FE_DIVBYZERO
-A divide-by-zero exception occurs when the program attempts to
-divide a finite non-zero number by zero.
-.It Dv FE_INEXACT
-An inexact exception is raised whenever there is a loss of precision
-due to rounding.
-.It Dv FE_INVALID
-Invalid operation exceptions occur when a program attempts to
-perform calculations for which there is no reasonable representable
-answer.
-For instance, subtraction of infinities, division of zero by zero,
-ordered comparison involving \*(Nas, and taking the square root of a
-negative number are all invalid operations.
-.It Dv FE_OVERFLOW
-An overflow exception occurs when the magnitude of the result of a
-computation is too large to fit in the destination type.
-.It Dv FE_UNDERFLOW
-Underflow occurs when the result of a computation is too close to zero
-to be represented as a non-zero value in the destination type.
-.El
-.Pp
-Additionally, the
-.Dv FE_ALL_EXCEPT
-macro expands to the bitwise OR of the above flags and any
-architecture-specific flags.
-Combinations of these flags are passed to the
-.Fn feclearexcept ,
-.Fn fegetexceptflag ,
-.Fn feraiseexcept ,
-.Fn fesetexceptflag ,
-and
-.Fn fetestexcept
-functions to clear, save, raise, restore, and examine the
-processor's floating-point exception flags, respectively.
-.Pp
-Exceptions may be
-.Em unmasked
-with
-.Fn feenableexcept
-and masked with
-.Fn fedisableexcept .
-Unmasked exceptions cause a trap when they are produced, and
-all exceptions are masked by default.
-The current mask can be tested with
-.Fn fegetexcept .
-.Ss Rounding Modes
-.St -ieee754
-specifies four rounding modes.
-These modes control the direction in which results are rounded
-from their exact values in order to fit them into binary
-floating-point variables.
-The four modes correspond with the following symbolic constants.
-.Bl -tag -width ".Dv FE_TOWARDZERO"
-.It Dv FE_TONEAREST
-Results are rounded to the closest representable value.
-If the exact result is exactly half way between two representable
-values, the value whose last binary digit is even (zero) is chosen.
-This is the default mode.
-.It Dv FE_DOWNWARD
-Results are rounded towards negative \*[If].
-.It Dv FE_UPWARD
-Results are rounded towards positive \*[If].
-.It Dv FE_TOWARDZERO
-Results are rounded towards zero.
-.El
-.Pp
-The
-.Fn fegetround
-and
-.Fn fesetround
-functions query and set the rounding mode.
-.Ss Environment Control
-The
-.Fn fegetenv
-and
-.Fn fesetenv
-functions save and restore the floating-point environment,
-which includes exception flags, the current exception mask,
-the rounding mode, and possibly other implementation-specific
-state.
-The
-.Fn feholdexcept
-function behaves like
-.Fn fegetenv ,
-but with the additional effect of clearing the exception flags and
-installing a
-.Em non-stop
-mode.
-In non-stop mode, floating-point operations will set exception flags
-as usual, but no
-.Dv SIGFPE
-signals will be generated as a result.
-Non-stop mode is the default, but it may be altered by
-non-standard mechanisms.
-.\" XXX Mention fe[gs]etmask() here after the interface is finalized
-.\" XXX and ready to be officially documented.
-The
-.Fn feupdateenv
-function restores a saved environment similarly to
-.Fn fesetenv ,
-but it also re-raises any floating-point exceptions from the old
-environment.
-.Pp
-The macro
-.Dv FE_DFL_ENV
-expands to a pointer to the default environment.
-.Sh CAVEATS
-The FENV_ACCESS pragma can be enabled with
-.Dl "#pragma STDC FENV_ACCESS ON"
-and disabled with the
-.Dl "#pragma STDC FENV_ACCESS OFF"
-directive.
-This lexically-scoped annotation tells the compiler that the program
-may access the floating-point environment, so optimizations that would
-violate strict IEEE-754 semantics are disabled.
-If execution reaches a block of code for which
-.Dv FENV_ACCESS
-is off, the floating-point environment will become undefined.
-.Sh EXAMPLES
-The following routine computes the square root function.
-It explicitly raises an invalid exception on appropriate inputs using
-.Fn feraiseexcept .
-It also defers inexact exceptions while it computes intermediate
-values, and then it allows an inexact exception to be raised only if
-the final answer is inexact.
-.Bd -literal -offset indent
-#pragma STDC FENV_ACCESS ON
-double sqrt(double n) {
-	double x = 1.0;
-	fenv_t env;
-
-	if (isnan(n) || n < 0.0) {
-		feraiseexcept(FE_INVALID);
-		return (NAN);
-	}
-	if (isinf(n) || n == 0.0)
-		return (n);
-	feholdexcept(&env);
-	while (fabs((x * x) - n) > DBL_EPSILON * 2 * x)
-		x = (x / 2) + (n / (2 * x));
-	if (x * x == n)
-		feclearexcept(FE_INEXACT);

-.Sh SYNOPSIS
-.In math.h
-.Ft double
-.Fn fma "double x" "double y" "double z"
-.Ft float
-.Fn fmaf "float x" "float y" "float z"
-.Ft long double
-.Fn fmal "long double x" "long double y" "long double z"
-.Sh DESCRIPTION
-The
-.Fn fma ,
-.Fn fmaf ,
-and
-.Fn fmal
-functions return
-.No "(x * y) + z" ,
-computed with only one rounding error.
-Using the ordinary multiplication and addition operators, by contrast,
-results in two roundings: one for the intermediate product and one for
-the final result.
-.Pp
-For instance, the expression
-.No "1.2e100 * 2.0e208 - 1.4e308"
-produces \*(If due to overflow in the intermediate product, whereas
-.No "fma(1.2e100, 2.0e208, -1.4e308)"
-returns approximately 1.0e308.
-.Pp
-The fused multiply-add operation is often used to improve the
-accuracy of calculations such as dot products.
-It may also be used to improve performance on machines that implement
-it natively.
-The macros
-.Dv FP_FAST_FMA ,
-.Dv FP_FAST_FMAF
-and
-.Dv FP_FAST_FMAL
-may be defined in
-.In math.h
-to indicate that
-.Fn fma ,
-.Fn fmaf ,
-and
-.Fn fmal
-(respectively) have comparable or faster speed than a multiply
-operation followed by an add operation.
-.Sh IMPLEMENTATION NOTES
-In general, these routines will behave as one would expect if
-.No "x * y + z"
-were computed with unbounded precision and range,
-then rounded to the precision of the return type.
-However, on some platforms, if
-.Fa z
-is \*(Na, these functions may not raise an exception even
-when the computation of
-.No "x * y"
-would have otherwise generated an invalid exception.

-.Sh LIBRARY
-.Lb libm
-.Sh SYNOPSIS
-.In math.h
-.Ft double
-.Fn hypot "double x" "double y"
-.Ft float
-.Fn hypotf "float x" "float y"
-.In complex.h
-.Ft double
-.Fn cabs "double complex z"
-.Ft float
-.Fn cabsf "float complex z"
-.Sh DESCRIPTION
-The
-.Fn hypot
-and
-.Fn hypotf
-functions
-compute the
-sqrt(x*x+y*y)
-in such a way that underflow will not happen, and overflow
-occurs only if the final result deserves it.
-The
-.Fn cabs
-and
-.Fn cabsf
-functions compute the complex absolute value of
-.Fa z .
-.Pp
-.Fn hypot "\*(If" "v"
-=
-.Fn hypot "v" "\*(If"
-= +\*(If for all
-.Fa v ,
-including \*(Na.
-.Sh ERROR (due to Roundoff, etc.)
-Below 0.97
-.Em ulps .
-Consequently
-.Fn hypot "5.0" "12.0"
-= 13.0
-exactly;
-in general, hypot and cabs return an integer whenever an
-integer might be expected.
-.Pp
-The same cannot be said for the shorter and faster version of hypot
-and cabs that is provided in the comments in cabs.c; its error can
-exceed 1.2
-.Em ulps .
-.Sh NOTES
-As might be expected,
-.Fn hypot "v" "\*(Na"
-and
-.Fn hypot "\*(Na" "v"
-are \*(Na for all
-.Em finite
-.Fa v .
-But programmers
-might be surprised at first to discover that
-.Fn hypot "\(+-\*(If" "\*(Na"
-= +\*(If.
-This is intentional; it happens because
-.Fn hypot "\*(If" "v"
-= +\*(If
-for
-.Em all
-.Fa v ,
-finite or infinite.
-Hence
-.Fn hypot "\*(If" "v"
-is independent of
-.Fa v .
-Unlike the reserved operand fault on a
-.Tn VAX ,
-the
-.Tn IEEE
-\*(Na is designed to
-disappear when it turns out to be irrelevant, as it does in
-.Fn hypot "\*(If" "\*(Na" .

-.Nd IEEE standard 754 for floating-point arithmetic
-.Sh DESCRIPTION
-The IEEE Standard 754 for Binary Floating-Point Arithmetic
-defines representations of floating-point numbers and abstract
-properties of arithmetic operations relating to precision,
-rounding, and exceptional cases, as described below.
-.Ss IEEE STANDARD 754 Floating-Point Arithmetic
-Radix: Binary.
-.Pp
-Overflow and underflow:
-.Bd -ragged -offset indent -compact
-Overflow goes by default to a signed \*(If.
-Underflow is
-.Em gradual .
-.Ed
-.Pp
-Zero is represented ambiguously as +0 or \-0.
-.Bd -ragged -offset indent -compact
-Its sign transforms correctly through multiplication or
-division, and is preserved by addition of zeros
-with like signs; but x\-x yields +0 for every
-finite x.
-The only operations that reveal zero's
-sign are division by zero and
-.Fn copysign x \(+-0 .
-In particular, comparison (x > y, x \(>= y, etc.)\&
-cannot be affected by the sign of zero; but if
-finite x = y then \*(If = 1/(x\-y) \(!= \-1/(y\-x) = \-\*(If.
-.Ed
-.Pp
-Infinity is signed.
-.Bd -ragged -offset indent -compact
-It persists when added to itself
-or to any finite number.
-Its sign transforms
-correctly through multiplication and division, and
-(finite)/\(+-\*(If\0=\0\(+-0
-(nonzero)/0 = \(+-\*(If.
-But
-\*(If\-\*(If, \*(If\(**0 and \*(If/\*(If
-are, like 0/0 and sqrt(\-3),
-invalid operations that produce \*(Na. ...
-.Ed
-.Pp
-Reserved operands (\*(Nas):
-.Bd -ragged -offset indent -compact
-An \*(Na is
-.Em ( N Ns ot Em a N Ns umber ) .
-Some \*(Nas, called Signaling \*(Nas, trap any floating-point operation
-performed upon them; they are used to mark missing
-or uninitialized values, or nonexistent elements
-of arrays.
-The rest are Quiet \*(Nas; they are
-the default results of Invalid Operations, and
-propagate through subsequent arithmetic operations.
-If x \(!= x then x is \*(Na; every other predicate
-(x > y, x = y, x < y, ...) is FALSE if \*(Na is involved.
-.Ed
-.Pp
-Rounding:
-.Bd -ragged -offset indent -compact
-Every algebraic operation (+, \-, \(**, /,
-\(sr)
-is rounded by default to within half an
-.Em ulp ,
-and when the rounding error is exactly half an
-.Em ulp
-then
-the rounded value's least significant bit is zero.
-(An
-.Em ulp
-is one
-.Em U Ns nit
-in the
-.Em L Ns ast
-.Em P Ns lace . )
-This kind of rounding is usually the best kind,
-sometimes provably so; for instance, for every
-x = 1.0, 2.0, 3.0, 4.0, ..., 2.0**52, we find
-(x/3.0)\(**3.0 == x and (x/10.0)\(**10.0 == x and ...
-despite that both the quotients and the products
-have been rounded.
-Only rounding like IEEE 754 can do that.
-But no single kind of rounding can be
-proved best for every circumstance, so IEEE 754
-provides rounding towards zero or towards
-+\*(If or towards \-\*(If
-at the programmer's option.
-.Ed
-.Pp
-Exceptions:
-.Bd -ragged -offset indent -compact
-IEEE 754 recognizes five kinds of floating-point exceptions,
-listed below in declining order of probable importance.
-.Bl -column -offset indent "Invalid Operation" "Gradual Underflow"
-.Em "Exception	Default Result"
-Invalid Operation	\*(Na, or FALSE
-Overflow	\(+-\*(If
-Divide by Zero	\(+-\*(If
-Underflow	Gradual Underflow
-Inexact	Rounded value
-.El
-.Pp
-NOTE: An Exception is not an Error unless handled
-badly.
-What makes a class of exceptions exceptional
-is that no single default response can be satisfactory
-in every instance.
-On the other hand, if a default
-response will serve most instances satisfactorily,
-the unsatisfactory instances cannot justify aborting
-computation every time the exception occurs.

-.Ed
-.Ss Additional Information Regarding Exceptions
-.Pp
-For each kind of floating-point exception, IEEE 754
-provides a Flag that is raised each time its exception
-is signaled, and stays raised until the program resets
-it.
-Programs may also test, save and restore a flag.
-Thus, IEEE 754 provides three ways by which programs
-may cope with exceptions for which the default result
-might be unsatisfactory:
-.Bl -enum
-.It
-Test for a condition that might cause an exception
-later, and branch to avoid the exception.
-.It
-Test a flag to see whether an exception has occurred
-since the program last reset its flag.
-.It
-Test a result to see whether it is a value that only
-an exception could have produced.
-.Pp
-CAUTION: The only reliable ways to discover
-whether Underflow has occurred are to test whether
-products or quotients lie closer to zero than the
-underflow threshold, or to test the Underflow
-flag.
-(Sums and differences cannot underflow in
-IEEE 754; if x \(!= y then x\-y is correct to
-full precision and certainly nonzero regardless of
-how tiny it may be.)
-Products and quotients that
-underflow gradually can lose accuracy gradually
-without vanishing, so comparing them with zero
-(as one might on a VAX) will not reveal the loss.
-Fortunately, if a gradually underflowed value is
-destined to be added to something bigger than the
-underflow threshold, as is almost always the case,
-digits lost to gradual underflow will not be missed
-because they would have been rounded off anyway.
-So gradual underflows are usually
-.Em provably
-ignorable.
-The same cannot be said of underflows flushed to 0.
-.El
-.Pp
-At the option of an implementor conforming to IEEE 754,
-other ways to cope with exceptions may be provided:
-.Bl -enum
-.It
-ABORT.
-This mechanism classifies an exception in
-advance as an incident to be handled by means
-traditionally associated with error-handling
-statements like "ON ERROR GO TO ...".
-Different
-languages offer different forms of this statement,
-but most share the following characteristics:
-.Bl -dash
-.It
-No means is provided to substitute a value for
-the offending operation's result and resume
-computation from what may be the middle of an
-expression.
-An exceptional result is abandoned.
-.It
-In a subprogram that lacks an error-handling
-statement, an exception causes the subprogram to
-abort within whatever program called it, and so
-on back up the chain of calling subprograms until
-an error-handling statement is encountered or the
-whole task is aborted and memory is dumped.
-.El
-.It
-STOP.
-This mechanism, requiring an interactive
-debugging environment, is more for the programmer
-than the program.
-It classifies an exception in
-advance as a symptom of a programmer's error; the
-exception suspends execution as near as it can to
-the offending operation so that the programmer can
-look around to see how it happened.
-Quite often
-the first several exceptions turn out to be quite
-unexceptionable, so the programmer ought ideally
-to be able to resume execution after each one as if
-execution had not been stopped.
-.It
-\&... Other ways lie beyond the scope of this document.
-.El
-.Pp
-Ideally, each
-elementary function should act as if it were indivisible, or
-atomic, in the sense that ...
-.Bl -enum
-.It
-No exception should be signaled that is not deserved by
-the data supplied to that function.
-.It
-Any exception signaled should be identified with that
-function rather than with one of its subroutines.
-.It
-The internal behavior of an atomic function should not
-be disrupted when a calling program changes from
-one to another of the five or so ways of handling
-exceptions listed above, although the definition
-of the function may be correlated intentionally
-with exception handling.
-.El
-.Pp
-The functions in
-.Nm libm
-are only approximately atomic.
-They signal no inappropriate exception except possibly ...
-.Bl -tag -width indent -offset indent -compact
-.It Xo
-Over/Underflow
-.Xc
-when a result, if properly computed, might have lain barely within range, and
-.It Xo
-Inexact in
-.Fn cabs ,
-.Fn cbrt ,
-.Fn hypot ,
-.Fn log10
-and
-.Fn pow
-.Xc
-when it happens to be exact, thanks to fortuitous cancellation of errors.
-.El
-Otherwise, ...
-.Bl -tag -width indent -offset indent -compact
-.It Xo
-Invalid Operation is signaled only when
-.Xc
-any result but \*(Na would probably be misleading.
-.It Xo
-Overflow is signaled only when
-.Xc
-the exact result would be finite but beyond the overflow threshold.
-.It Xo
-Divide-by-Zero is signaled only when
-.Xc
-a function takes exactly infinite values at finite operands.
-.It Xo
-Underflow is signaled only when
-.Xc
-the exact result would be nonzero but tinier than the underflow threshold.
-.It Xo
-Inexact is signaled only when
-.Xc
-greater range or precision would be needed to represent the exact result.

-The external integer
-.Fa signgam
-returns the sign of \(*G(x).
-.Pp
-.Fn lgamma_r x signgamp
-and
-.Fn lgammaf_r x signgamp
-provide the same functionality as

-are deprecated aliases for
-.Fn lgamma ,

-.Fn tgamma x
-returns \(*G(x), with no effect on
-.Fa signgam .
-.Sh IDIOSYNCRASIES
-Do not use the expression
-.Dq Li signgam\(**exp(lgamma(x))
-to compute g := \(*G(x).
-Instead use a program like this (in C):
-.Bd -literal -offset indent
-lg = lgamma(x); g = signgam\(**exp(lg);
-.Ed
-.Pp
-Only after
-.Fn lgamma
-or
-.Fn lgammaf
-has returned can signgam be correct.
-.Pp
-For arguments in its range,
-.Fn tgamma
-is preferred, as for positive arguments
-it is accurate to within one unit in the last place.
-Exponentiation of
-.Fn lgamma
-will lose up to 10 significant bits.

-.Fn gamma_r ,
-.Fn gammaf ,
-.Fn gammaf_r ,
-.Fn lgamma ,
-.Fn lgamma_r ,
-.Fn lgammaf ,
-and
-.Fn lgammaf_r
-return appropriate values unless an argument is out of range.
-Overflow will occur for sufficiently large positive values, and
-non-positive integers.
-For large non-integer negative values,

-will underflow.
-.Sh SEE ALSO

-.Sh HISTORY
-A math library with many of the present functions appeared in
-.At v7 .
-The library was substantially rewritten for
-.Bx 4.3
-to provide
-better accuracy and speed on machines supporting either VAX
-or IEEE 754 floating-point.
-Most of this library was replaced with FDLIBM, developed at Sun
-Microsystems, in
-.Fx 1.1.5 .
-Additional routines, including ones for
-.Vt float
-and
-.Vt long double
-values, were written for or imported into subsequent versions of FreeBSD.
-.Sh BUGS
-The
-.Fn log2
-and
-.Fn nan
-functions are missing, and many functions are not available in their
-.Vt "long double"
-variants.
-.Pp
-Many of the routines to compute transcendental functions produce
-inaccurate results in other than the default rounding mode.
-.Pp
-On some architectures, trigonometric argument reduction is not
-performed accurately, resulting in errors greater than 1
-.Em ulp
-for large arguments to
-.Fn cos ,
-.Fn sin ,
-and
-.Fn tan .

-/* __ieee754_exp(x)
- * Returns the exponential of x.
- *
- * Method
- *   1. Argument reduction:
- *      Reduce x to an r so that |r| <= 0.5*ln2 ~ 0.34658.
- *	Given x, find r and integer k such that
- *
- *               x = k*ln2 + r,  |r| <= 0.5*ln2.  
- *
- *      Here r will be represented as r = hi-lo for better 
- *	accuracy.
- *
- *   2. Approximation of exp(r) by a special rational function on
- *	the interval [0,0.34658]:
- *	Write
- *	    R(r**2) = r*(exp(r)+1)/(exp(r)-1) = 2 + r*r/6 - r**4/360 + ...
- *      We use a special Remes algorithm on [0,0.34658] to generate 
- * 	a polynomial of degree 5 to approximate R. The maximum error 
- *	of this polynomial approximation is bounded by 2**-59. In
- *	other words,
- *	    R(z) ~ 2.0 + P1*z + P2*z**2 + P3*z**3 + P4*z**4 + P5*z**5
- *  	(where z=r*r, and the values of P1 to P5 are listed below)
- *	and
- *	    |                  5          |     -59
- *	    | 2.0+P1*z+...+P5*z   -  R(z) | <= 2 
- *	    |                             |
- *	The computation of exp(r) thus becomes
- *                             2*r
- *		exp(r) = 1 + -------
- *		              R - r
- *                                 r*R1(r)	
- *		       = 1 + r + ----------- (for better accuracy)
- *		                  2 - R1(r)
- *	where
- *			         2       4             10
- *		R1(r) = r - (P1*r  + P2*r  + ... + P5*r   ).
- *	
- *   3. Scale back to obtain exp(x):
- *	From step 1, we have
- *	   exp(x) = 2^k * exp(r)
- *
- * Special cases:
- *	exp(INF) is INF, exp(NaN) is NaN;
- *	exp(-INF) is 0, and
- *	for finite argument, only exp(0)=1 is exact.
- *
- * Accuracy:
- *	according to an error analysis, the error is always less than
- *	1 ulp (unit in the last place).
- *
- * Misc. info.
- *	For IEEE double 
- *	    if x >  7.09782712893383973096e+02 then exp(x) overflow
- *	    if x < -7.45133219101941108420e+02 then exp(x) underflow
- *
- * Constants:
- * The hexadecimal values are the intended ones for the following 
- * constants. The decimal values may be used, provided that the 
- * compiler will convert from decimal to binary accurately enough
- * to produce the hexadecimal values shown.

- *	Assume x>y>0;
- *	(if possible, set rounding to round-to-nearest)

-/* __ieee754_j1(x), __ieee754_y1(x)
- * Bessel function of the first and second kinds of order zero.
- * Method -- j1(x):
- *	1. For tiny x, we use j1(x) = x/2 - x^3/16 + x^5/384 - ...
- *	2. Reduce x to |x| since j1(x)=-j1(-x),  and
- *	   for x in (0,2)
- *		j1(x) = x/2 + x*z*R0/S0,  where z = x*x;
- *	   (precision:  |j1/x - 1/2 - R0/S0 |<2**-61.51 )
- *	   for x in (2,inf)
- * 		j1(x) = sqrt(2/(pi*x))*(p1(x)*cos(x1)-q1(x)*sin(x1))
- * 		y1(x) = sqrt(2/(pi*x))*(p1(x)*sin(x1)+q1(x)*cos(x1))
- * 	   where x1 = x-3*pi/4. It is better to compute sin(x1),cos(x1)
- *	   as follow:
- *		cos(x1) =  cos(x)cos(3pi/4)+sin(x)sin(3pi/4)
- *			=  1/sqrt(2) * (sin(x) - cos(x))
- *		sin(x1) =  sin(x)cos(3pi/4)-cos(x)sin(3pi/4)
- *			= -1/sqrt(2) * (sin(x) + cos(x))
- * 	   (To avoid cancellation, use
- *		sin(x) +- cos(x) = -cos(2x)/(sin(x) -+ cos(x))
- * 	    to compute the worse one.)
- *	   
- *	3 Special cases
- *		j1(nan)= nan
- *		j1(0) = 0
- *		j1(inf) = 0
- *		
- * Method -- y1(x):
- *	1. screen out x<=0 cases: y1(0)=-inf, y1(x<0)=NaN 
- *	2. For x<2.
- *	   Since 
- *		y1(x) = 2/pi*(j1(x)*(ln(x/2)+Euler)-1/x-x/2+5/64*x^3-...)
- *	   therefore y1(x)-2/pi*j1(x)*ln(x)-1/x is an odd function.
- *	   We use the following function to approximate y1,
- *		y1(x) = x*U(z)/V(z) + (2/pi)*(j1(x)*ln(x)-1/x), z= x^2
- *	   where for x in [0,2] (abs err less than 2**-65.89)
- *		U(z) = U0[0] + U0[1]*z + ... + U0[4]*z^4
- *		V(z) = 1  + v0[0]*z + ... + v0[4]*z^5
- *	   Note: For tiny x, 1/x dominate y1 and hence
- *		y1(tiny) = -2/pi/tiny, (choose tiny<2**-54)
- *	3. For x>=2.
- * 		y1(x) = sqrt(2/(pi*x))*(p1(x)*sin(x1)+q1(x)*cos(x1))
- * 	   where x1 = x-3*pi/4. It is better to compute sin(x1),cos(x1)
- *	   by method mentioned above.

-/* __ieee754_lgamma_r(x, signgamp)
- * Reentrant version of the logarithm of the Gamma function 
- * with user provide pointer for the sign of Gamma(x). 
- *
- * Method:
- *   1. Argument Reduction for 0 < x <= 8
- * 	Since gamma(1+s)=s*gamma(s), for x in [0,8], we may 
- * 	reduce x to a number in [1.5,2.5] by
- * 		lgamma(1+s) = log(s) + lgamma(s)
- *	for example,
- *		lgamma(7.3) = log(6.3) + lgamma(6.3)
- *			    = log(6.3*5.3) + lgamma(5.3)
- *			    = log(6.3*5.3*4.3*3.3*2.3) + lgamma(2.3)
- *   2. Polynomial approximation of lgamma around its
- *	minimun ymin=1.461632144968362245 to maintain monotonicity.
- *	On [ymin-0.23, ymin+0.27] (i.e., [1.23164,1.73163]), use
- *		Let z = x-ymin;
- *		lgamma(x) = -1.214862905358496078218 + z^2*poly(z)
- *	where
- *		poly(z) is a 14 degree polynomial.
- *   2. Rational approximation in the primary interval [2,3]
- *	We use the following approximation:
- *		s = x-2.0;
- *		lgamma(x) = 0.5*s + s*P(s)/Q(s)
- *	with accuracy
- *		|P/Q - (lgamma(x)-0.5s)| < 2**-61.71
- *	Our algorithms are based on the following observation
- *
- *                             zeta(2)-1    2    zeta(3)-1    3
- * lgamma(2+s) = s*(1-Euler) + --------- * s  -  --------- * s  + ...
- *                                 2                 3
- *
- *	where Euler = 0.5771... is the Euler constant, which is very
- *	close to 0.5.
- *
- *   3. For x>=8, we have
- *	lgamma(x)~(x-0.5)log(x)-x+0.5*log(2pi)+1/(12x)-1/(360x**3)+....
- *	(better formula:
- *	   lgamma(x)~(x-0.5)*(log(x)-1)-.5*(log(2pi)-1) + ...)
- *	Let z = 1/x, then we approximation
- *		f(z) = lgamma(x) - (x-0.5)(log(x)-1)
- *	by
- *	  			    3       5             11
- *		w = w0 + w1*z + w2*z  + w3*z  + ... + w6*z
- *	where 
- *		|w - f(z)| < 2**-58.74
- *		
- *   4. For negative x, since (G is gamma function)
- *		-x*G(-x)*G(x) = pi/sin(pi*x),
- * 	we have
- * 		G(x) = pi/(sin(pi*x)*(-x)*G(-x))
- *	since G(-x) is positive, sign(G(x)) = sign(sin(pi*x)) for x<0
- *	Hence, for x<0, signgam = sign(sin(pi*x)) and 
- *		lgamma(x) = log(|Gamma(x)|)
- *			  = log(pi/(|x*sin(pi*x)|)) - lgamma(-x);
- *	Note: one should avoid compute pi*(-x) directly in the 
- *	      computation of sin(pi*(-x)).
- *		
- *   5. Special Cases
- *		lgamma(2+s) ~ s*(1-Euler) for tiny s
- *		lgamma(1)=lgamma(2)=0
- *		lgamma(x) ~ -log(x) for tiny x
- *		lgamma(0) = lgamma(inf) = inf
- *	 	lgamma(-integer) = +-inf

-/* __ieee754_log(x)
- * Return the logrithm of x
- *
- * Method :                  
- *   1. Argument Reduction: find k and f such that 
- *			x = 2^k * (1+f), 
- *	   where  sqrt(2)/2 < 1+f < sqrt(2) .
- *
- *   2. Approximation of log(1+f).
- *	Let s = f/(2+f) ; based on log(1+f) = log(1+s) - log(1-s)
- *		 = 2s + 2/3 s**3 + 2/5 s**5 + .....,
- *	     	 = 2s + s*R
- *      We use a special Reme algorithm on [0,0.1716] to generate 
- * 	a polynomial of degree 14 to approximate R The maximum error 
- *	of this polynomial approximation is bounded by 2**-58.45. In
- *	other words,
- *		        2      4      6      8      10      12      14
- *	    R(z) ~ Lg1*s +Lg2*s +Lg3*s +Lg4*s +Lg5*s  +Lg6*s  +Lg7*s
- *  	(the values of Lg1 to Lg7 are listed in the program)
- *	and
- *	    |      2          14          |     -58.45
- *	    | Lg1*s +...+Lg7*s    -  R(z) | <= 2 
- *	    |                             |
- *	Note that 2s = f - s*f = f - hfsq + s*hfsq, where hfsq = f*f/2.
- *	In order to guarantee error in log below 1ulp, we compute log
- *	by
- *		log(1+f) = f - s*(f - R)	(if f is not too large)
- *		log(1+f) = f - (hfsq - s*(hfsq+R)).	(better accuracy)
- *	
- *	3. Finally,  log(x) = k*ln2 + log(1+f).  
- *			    = k*ln2_hi+(f-(hfsq-(s*(hfsq+R)+k*ln2_lo)))
- *	   Here ln2 is split into two floating point number: 
- *			ln2_hi + ln2_lo,
- *	   where n*ln2_hi is always exact for |n| < 2000.
- *
- * Special cases:
- *	log(x) is NaN with signal if x < 0 (including -INF) ; 
- *	log(+INF) is +INF; log(0) is -INF with signal;
- *	log(NaN) is that NaN with no signal.
- *
- * Accuracy:
- *	according to an error analysis, the error is always less than
- *	1 ulp (unit in the last place).
- *
- * Constants:
- * The hexadecimal values are the intended ones for the following 
- * constants. The decimal values may be used, provided that the 
- * compiler will convert from decimal to binary accurately enough 
- * to produce the hexadecimal values shown.

- * Method:  Let x =  2   * (1+f)
- *	1. Compute and return log2(x) in two pieces:
- *		log2(x) = w1 + w2,
- *	   where w1 has 53-24 = 29 bit trailing zeros.
- *	2. Perform y*log2(x) = n+y' by simulating muti-precision 
- *	   arithmetic, where |y'|<=0.5.
- *	3. Return x**y = 2**n*exp(y'*log2)
- *
- * Special cases:
- *	1.  (anything) ** 0  is 1
- *	2.  (anything) ** 1  is itself
- *	3.  (anything) ** NAN is NAN
- *	4.  NAN ** (anything except 0) is NAN
- *	5.  +-(|x| > 1) **  +INF is +INF
- *	6.  +-(|x| > 1) **  -INF is +0
- *	7.  +-(|x| < 1) **  +INF is +0
- *	8.  +-(|x| < 1) **  -INF is +INF
- *	9.  +-1         ** +-INF is NAN
- *	10. +0 ** (+anything except 0, NAN)               is +0
- *	11. -0 ** (+anything except 0, NAN, odd integer)  is +0
- *	12. +0 ** (-anything except 0, NAN)               is +INF
- *	13. -0 ** (-anything except 0, NAN, odd integer)  is +INF
- *	14. -0 ** (odd integer) = -( +0 ** (odd integer) )
- *	15. +INF ** (+anything except 0,NAN) is +INF
- *	16. +INF ** (-anything except 0,NAN) is +0
- *	17. -INF ** (anything)  = -0 ** (-anything)
- *	18. (-anything) ** (integer) is (-1)**(integer)*(+anything**integer)
- *	19. (-anything except 0 and inf) ** (non-integer) is NAN
- *
- * Accuracy:
- *	pow(x,y) returns x**y nearly rounded. In particular
- *			pow(integer,integer)
- *	always returns the correct integer provided it is 
- *	representable.
- *
- * Constants :
- * The hexadecimal values are the intended ones for the following 
- * constants. The decimal values may be used, provided that the 
- * compiler will convert from decimal to binary accurately enough 
- * to produce the hexadecimal values shown.

- * Return correctly rounded sqrt.
- *           ------------------------------------------
- *	     |  Use the hardware sqrt if you have one |
- *           ------------------------------------------
- * Method: 
- *   Bit by bit method using integer arithmetic. (Slow, but portable) 
- *   1. Normalization
- *	Scale x to y in [1,4) with even powers of 2: 
- *	find an integer k such that  1 <= (y=x*2^(2k)) < 4, then
- *		sqrt(x) = 2^k * sqrt(y)
- *   2. Bit by bit computation
- *	Let q  = sqrt(y) truncated to i bit after binary point (q = 1),
- *	     i							 0
- *                                     i+1         2
- *	    s  = 2*q , and	y  =  2   * ( y - q  ).		(1)
- *	     i      i            i                 i
- *                                                        
- *	To compute q    from q , one checks whether 
- *		    i+1       i                       
- *
- *			      -(i+1) 2
- *			(q + 2      ) <= y.			(2)
- *     			  i
- *							      -(i+1)
- *	If (2) is false, then q   = q ; otherwise q   = q  + 2      .
- *		 	       i+1   i             i+1   i
- *
- *	With some algebric manipulation, it is not difficult to see
- *	that (2) is equivalent to 
- *                             -(i+1)
- *			s  +  2       <= y			(3)
- *			 i                i
- *
- *	The advantage of (3) is that s  and y  can be computed by 
- *				      i      i
- *	the following recurrence formula:
- *	    if (3) is false
- *
- *	    s     =  s  ,	y    = y   ;			(4)
- *	     i+1      i		 i+1    i
- *
- *	    otherwise,
- *                         -i                     -(i+1)
- *	    s	  =  s  + 2  ,  y    = y  -  s  - 2  		(5)
- *           i+1      i          i+1    i     i
- *				
- *	One may easily use induction to prove (4) and (5). 
- *	Note. Since the left hand side of (3) contain only i+2 bits,
- *	      it does not necessary to do a full (53-bit) comparison 
- *	      in (3).
- *   3. Final rounding
- *	After generating the 53 bits result, we compute one more bit.
- *	Together with the remainder, we can decide whether the
- *	result is exact, bigger than 1/2ulp, or less than 1/2ulp
- *	(it will never equal to 1/2ulp).
- *	The rounding mode can be detected by checking whether
- *	huge + tiny is equal to huge, and whether huge - tiny is
- *	equal to huge for some floating point number "huge" and "tiny".
- *		
- * Special cases:
- *	sqrt(+-0) = +-0 	... exact
- *	sqrt(inf) = inf
- *	sqrt(-ve) = NaN		... with invalid signal
- *	sqrt(NaN) = NaN		... with invalid signal for signaling NaN
- *

-Other methods  (use floating-point arithmetic)
--------------
-(This is a copy of a drafted paper by Prof W. Kahan 
-and K.C. Ng, written in May, 1986)
-
-	Two algorithms are given here to implement sqrt(x) 
-	(IEEE double precision arithmetic) in software.
-	Both supply sqrt(x) correctly rounded. The first algorithm (in
-	Section A) uses newton iterations and involves four divisions.
-	The second one uses reciproot iterations to avoid division, but
-	requires more multiplications. Both algorithms need the ability
-	to chop results of arithmetic operations instead of round them, 
-	and the INEXACT flag to indicate when an arithmetic operation
-	is executed exactly with no roundoff error, all part of the 
-	standard (IEEE 754-1985). The ability to perform shift, add,
-	subtract and logical AND operations upon 32-bit words is needed
-	too, though not part of the standard.
-
-A.  sqrt(x) by Newton Iteration
-
-   (1)	Initial approximation
-
-	Let x0 and x1 be the leading and the trailing 32-bit words of
-	a floating point number x (in IEEE double format) respectively 
-
-	    1    11		     52				  ...widths
-	   ------------------------------------------------------
-	x: |s|	  e     |	      f				|
-	   ------------------------------------------------------
-	      msb    lsb  msb				      lsb ...order
-
- 
-	     ------------------------  	     ------------------------
-	x0:  |s|   e    |    f1     |	 x1: |          f2           |
-	     ------------------------  	     ------------------------
-
-	By performing shifts and subtracts on x0 and x1 (both regarded
-	as integers), we obtain an 8-bit approximation of sqrt(x) as
-	follows.
-
-		k  := (x0>>1) + 0x1ff80000;
-		y0 := k - T1[31&(k>>15)].	... y ~ sqrt(x) to 8 bits
-	Here k is a 32-bit integer and T1[] is an integer array containing
-	correction terms. Now magically the floating value of y (y's
-	leading 32-bit word is y0, the value of its trailing word is 0)
-	approximates sqrt(x) to almost 8-bit.
-
-	Value of T1:
-	static int T1[32]= {
-	0,	1024,	3062,	5746,	9193,	13348,	18162,	23592,
-	29598,	36145,	43202,	50740,	58733,	67158,	75992,	85215,
-	83599,	71378,	60428,	50647,	41945,	34246,	27478,	21581,
-	16499,	12183,	8588,	5674,	3403,	1742,	661,	130,};
-
-    (2)	Iterative refinement
-
-	Apply Heron's rule three times to y, we have y approximates 
-	sqrt(x) to within 1 ulp (Unit in the Last Place):
-
-		y := (y+x/y)/2		... almost 17 sig. bits
-		y := (y+x/y)/2		... almost 35 sig. bits
-		y := y-(y-x/y)/2	... within 1 ulp
-
-
-	Remark 1.
-	    Another way to improve y to within 1 ulp is:
-
-		y := (y+x/y)		... almost 17 sig. bits to 2*sqrt(x)
-		y := y - 0x00100006	... almost 18 sig. bits to sqrt(x)
-
-				2
-			    (x-y )*y
-		y := y + 2* ----------	...within 1 ulp
-			       2
-			     3y  + x
-
-
-	This formula has one division fewer than the one above; however,
-	it requires more multiplications and additions. Also x must be
-	scaled in advance to avoid spurious overflow in evaluating the
-	expression 3y*y+x. Hence it is not recommended uless division
-	is slow. If division is very slow, then one should use the 
-	reciproot algorithm given in section B.
-
-    (3) Final adjustment
-
-	By twiddling y's last bit it is possible to force y to be 
-	correctly rounded according to the prevailing rounding mode
-	as follows. Let r and i be copies of the rounding mode and
-	inexact flag before entering the square root program. Also we
-	use the expression y+-ulp for the next representable floating
-	numbers (up and down) of y. Note that y+-ulp = either fixed
-	point y+-1, or multiply y by nextafter(1,+-inf) in chopped
-	mode.
-
-		I := FALSE;	... reset INEXACT flag I
-		R := RZ;	... set rounding mode to round-toward-zero
-		z := x/y;	... chopped quotient, possibly inexact
-		If(not I) then {	... if the quotient is exact
-		    if(z=y) {
-		        I := i;	 ... restore inexact flag
-		        R := r;  ... restore rounded mode
-		        return sqrt(x):=y.
-		    } else {
-			z := z - ulp;	... special rounding
-		    }
-		}
-		i := TRUE;		... sqrt(x) is inexact
-		If (r=RN) then z=z+ulp	... rounded-to-nearest
-		If (r=RP) then {	... round-toward-+inf
-		    y = y+ulp; z=z+ulp;
-		}
-		y := y+z;		... chopped sum
-		y0:=y0-0x00100000;	... y := y/2 is correctly rounded.
-	        I := i;	 		... restore inexact flag
-	        R := r;  		... restore rounded mode
-	        return sqrt(x):=y.
-		    
-    (4)	Special cases
-
-	Square root of +inf, +-0, or NaN is itself;
-	Square root of a negative number is NaN with invalid signal.
-
-
-B.  sqrt(x) by Reciproot Iteration
-
-   (1)	Initial approximation
-
-	Let x0 and x1 be the leading and the trailing 32-bit words of
-	a floating point number x (in IEEE double format) respectively
-	(see section A). By performing shifs and subtracts on x0 and y0,
-	we obtain a 7.8-bit approximation of 1/sqrt(x) as follows.
-
-	    k := 0x5fe80000 - (x0>>1);
-	    y0:= k - T2[63&(k>>14)].	... y ~ 1/sqrt(x) to 7.8 bits
-
-	Here k is a 32-bit integer and T2[] is an integer array 
-	containing correction terms. Now magically the floating
-	value of y (y's leading 32-bit word is y0, the value of
-	its trailing word y1 is set to zero) approximates 1/sqrt(x)
-	to almost 7.8-bit.
-
-	Value of T2:
-	static int T2[64]= {
-	0x1500,	0x2ef8,	0x4d67,	0x6b02,	0x87be,	0xa395,	0xbe7a,	0xd866,
-	0xf14a,	0x1091b,0x11fcd,0x13552,0x14999,0x15c98,0x16e34,0x17e5f,
-	0x18d03,0x19a01,0x1a545,0x1ae8a,0x1b5c4,0x1bb01,0x1bfde,0x1c28d,
-	0x1c2de,0x1c0db,0x1ba73,0x1b11c,0x1a4b5,0x1953d,0x18266,0x16be0,
-	0x1683e,0x179d8,0x18a4d,0x19992,0x1a789,0x1b445,0x1bf61,0x1c989,
-	0x1d16d,0x1d77b,0x1dddf,0x1e2ad,0x1e5bf,0x1e6e8,0x1e654,0x1e3cd,

-	0x1527f,0x1334a,0x11051,0xe951,	0xbe01,	0x8e0d,	0x5924,	0x1edd,};
-
-    (2)	Iterative refinement
-
-	Apply Reciproot iteration three times to y and multiply the
-	result by x to get an approximation z that matches sqrt(x)
-	to about 1 ulp. To be exact, we will have 
-		-1ulp < sqrt(x)-z<1.0625ulp.
-	
-	... set rounding mode to Round-to-nearest
-	   y := y*(1.5-0.5*x*y*y)	... almost 15 sig. bits to 1/sqrt(x)
-	   y := y*((1.5-2^-30)+0.5*x*y*y)... about 29 sig. bits to 1/sqrt(x)
-	... special arrangement for better accuracy
-	   z := x*y			... 29 bits to sqrt(x), with z*y<1
-	   z := z + 0.5*z*(1-z*y)	... about 1 ulp to sqrt(x)
-
-	Remark 2. The constant 1.5-2^-30 is chosen to bias the error so that
-	(a) the term z*y in the final iteration is always less than 1; 
-	(b) the error in the final result is biased upward so that
-		-1 ulp < sqrt(x) - z < 1.0625 ulp
-	    instead of |sqrt(x)-z|<1.03125ulp.
-
-    (3)	Final adjustment
-
-	By twiddling y's last bit it is possible to force y to be 
-	correctly rounded according to the prevailing rounding mode
-	as follows. Let r and i be copies of the rounding mode and
-	inexact flag before entering the square root program. Also we
-	use the expression y+-ulp for the next representable floating
-	numbers (up and down) of y. Note that y+-ulp = either fixed
-	point y+-1, or multiply y by nextafter(1,+-inf) in chopped
-	mode.
-
-	R := RZ;		... set rounding mode to round-toward-zero
-	switch(r) {
-	    case RN:		... round-to-nearest
-	       if(x<= z*(z-ulp)...chopped) z = z - ulp; else
-	       if(x<= z*(z+ulp)...chopped) z = z; else z = z+ulp;
-	       break;
-	    case RZ:case RM:	... round-to-zero or round-to--inf
-	       R:=RP;		... reset rounding mod to round-to-+inf
-	       if(x<z*z ... rounded up) z = z - ulp; else
-	       if(x>=(z+ulp)*(z+ulp) ...rounded up) z = z+ulp;
-	       break;
-	    case RP:		... round-to-+inf
-	       if(x>(z+ulp)*(z+ulp)...chopped) z = z+2*ulp; else
-	       if(x>z*z ...chopped) z = z+ulp;
-	       break;
-	}
-
-	Remark 3. The above comparisons can be done in fixed point. For
-	example, to compare x and w=z*z chopped, it suffices to compare
-	x1 and w1 (the trailing parts of x and w), regarding them as
-	two's complement integers.
-
-	...Is z an exact square root?
-	To determine whether z is an exact square root of x, let z1 be the
-	trailing part of z, and also let x0 and x1 be the leading and
-	trailing parts of x.
-
-	If ((z1&0x03ffffff)!=0)	... not exact if trailing 26 bits of z!=0
-	    I := 1;		... Raise Inexact flag: z is not exact
-	else {
-	    j := 1 - [(x0>>20)&1]	... j = logb(x) mod 2
-	    k := z1 >> 26;		... get z's 25-th and 26-th 
-					    fraction bits
-	    I := i or (k&j) or ((k&(j+j+1))!=(x1&3));
-	}
-	R:= r		... restore rounded mode
-	return sqrt(x):=z.
-
-	If multiplication is cheaper then the foregoing red tape, the 
-	Inexact flag can be evaluated by
-
-	    I := i;
-	    I := (z*z!=x) or I.
-
-	Note that z*z can overwrite I; this value must be sensed if it is 
-	True.
-
-	Remark 4. If z*z = x exactly, then bit 25 to bit 0 of z1 must be
-	zero.
-
-		    --------------------
-		z1: |        f2        | 
-		    --------------------
-		bit 31		   bit 0
-
-	Further more, bit 27 and 26 of z1, bit 0 and 1 of x1, and the odd
-	or even of logb(x) have the following relations:
-
-	-------------------------------------------------
-	bit 27,26 of z1		bit 1,0 of x1	logb(x)
-	-------------------------------------------------
-	00			00		odd and even
-	01			01		even
-	10			10		odd
-	10			00		even
-	11			01		even
-	-------------------------------------------------

- *
- * (2/pi) is represented by an array of 24-bit integers in ipio2[].
- *
- * Input parameters:
- * 	x[]	The input value (must be positive) is broken into nx 
- *		pieces of 24-bit integers in double precision format.
- *		x[i] will be the i-th 24 bit of x. The scaled exponent 
- *		of x[0] is given in input parameter e0 (i.e., x[0]*2^e0 
- *		match x's up to 24 bits.
- *
- *		Example of breaking a double positive z into x[0]+x[1]+x[2]:
- *			e0 = ilogb(z)-23
- *			z  = scalbn(z,-e0)
- *		for i = 0,1,2
- *			x[i] = floor(z)
- *			z    = (z-x[i])*2**24

- *			24-bit  precision	1
- *			53-bit  precision	2
- *			64-bit  precision	2
- *			113-bit precision	3
- *		The actual value is the sum of them. Thus for 113-bit
- *		precison, one may have to do something like:
- *
- *		long double t,w,r_head, r_tail;
- *		t = (long double)y[2] + (long double)y[1];
- *		w = (long double)y[0];
- *		r_head = t+w;
- *		r_tail = w - (r_head - t);
- *
- *	e0	The exponent of x[0]
- *
- *	nx	dimension of x[]
- *
- *  	prec	an integer indicating the precision:
- *			0	24  bits (single)
- *			1	53  bits (double)
- *			2	64  bits (extended)
- *			3	113 bits (quad)
- *
- *	ipio2[]
- *		integer array, contains the (24*i)-th to (24*i+23)-th

- *
- *			ipio2[i] * 2^(-24(i+1)).
- *
- * External function:
- *	double scalbn(), floor();
- *
- *
- * Here is the description of some local variables:
- *
- * 	jk	jk+1 is the initial number of terms of ipio2[] needed
- *		in the computation. The recommended value is 2,3,4,
- *		6 for single, double, extended,and quad.
- *
- * 	jz	local integer variable indicating the number of 
- *		terms of ipio2[] used. 
- *
- *	jx	nx - 1
- *
- *	jv	index for pointing to the suitable ipio2[] for the
- *		computation. In general, we want
- *			( 2^e0*x[0] * ipio2[jv-1]*2^(-24jv) )/8
- *		is an integer. Thus
- *			e0-3-24*jv >= 0 or (e0-3)/24 >= jv
- *		Hence jv = max(0,(e0-3)/24).
- *
- *	jp	jp+1 is the number of terms in PIo2[] needed, jp = jk.
- *
- * 	q[]	double array with integral value, representing the
- *		24-bits chunk of the product of x and 2/pi.
- *
- *	q0	the corresponding exponent of q[0]. Note that the
- *		exponent for q[i] would be q0-24*i.
- *
- *	PIo2[]	double precision array, obtained by cutting pi/2
- *		into 24 bits chunks. 
- *
- *	f[]	ipio2[] in floating point 
- *
- *	iq[]	integer array by breaking up q[] in 24-bits chunk.
- *
- *	fq[]	final product of x*(2/pi) in fq[0],..,fq[jk]

- * kernel tan function on ~[-pi/4, pi/4] (except on -0), pi/4 ~ 0.7854
- * Input x is assumed to be bounded by ~pi/4 in magnitude.
- * Input y is the tail of x.
- * Input k indicates whether tan (if k = 1) or -1/tan (if k = -1) is returned.
- *
- * Algorithm
- *	1. Since tan(-x) = -tan(x), we need only to consider positive x.
- *	2. Callers must return tan(-0) = -0 without calling here since our
- *	   odd polynomial is not evaluated in a way that preserves -0.
- *	   Callers may do the optimization tan(x) ~ x for tiny x.
- *	3. tan(x) is approximated by a odd polynomial of degree 27 on
- *	   [0,0.67434]
- *		  	         3             27
- *	   	tan(x) ~ x + T1*x + ... + T13*x
- *	   where
- *
- * 	        |tan(x)         2     4            26   |     -59.2
- * 	        |----- - (1+T1*x +T2*x +.... +T13*x    )| <= 2
- * 	        |  x 					|
- *
- *	   Note: tan(x+y) = tan(x) + tan'(x)*y
- *		          ~ tan(x) + (1+x*x)*y
- *	   Therefore, for better accuracy in computing tan(x+y), let
- *		     3      2      2       2       2
- *		r = x *(T2+x *(T3+x *(...+x *(T12+x *T13))))
- *	   then
- *		 		    3    2
- *		tan(x+y) = x + (T1*x + (x *(r+y)+y))
- *
- *      4. For x in [0.67434,pi/4],  let y = pi/4 - x, then
- *		tan(x) = tan(pi/4-y) = (1-tan(y))/(1+tan(y))
- *		       = 1 - 2*(tan(y) - (tan(y)^2)/(1+tan(y)))

- *
- *      Note1:
- *	   To compute exp(-x*x-0.5625+R/S), let s be a single
- *	   precision number and s := x; then

- *			  exp(-x*x)
- *		erfc(x) ~ ---------- * ( 1 + Poly(1/x^2) )
- *			  x*sqrt(pi)
- *	   We use rational approximation to approximate
- *      	g(s)=f(1/x^2) = log(erfc(x)*x) - x*x + 0.5625
- *	   Here is the error bound for R1/S1 and R2/S2
- *      	|R1/S1 - f(x)|  < 2**(-62.57)
- *      	|R2/S2 - f(x)|  < 2**(-61.52)
- *
- *      5. For inf > x >= 28

- *         	erfc(0) = 1, erfc(inf) = 0, erfc(-inf) = 2,

- * exp2(x): compute the base 2 exponential of x
- *
- * Accuracy: Peak error < 0.503 ulp for normalized results.
- *
- * Method: (accurate tables)
- *
- *   Reduce x:
- *     x = 2**k + y, for integer k and |y| <= 1/2.
- *     Thus we have exp2(x) = 2**k * exp2(y).
- *
- *   Reduce y:
- *     y = i/TBLSIZE + z - eps[i] for integer i near y * TBLSIZE.
- *     Thus we have exp2(y) = exp2(i/TBLSIZE) * exp2(z - eps[i]),
- *     with |z - eps[i]| <= 2**-9 + 2**-39 for the table used.
- *
- *   We compute exp2(i/TBLSIZE) via table lookup and exp2(z - eps[i]) via
- *   a degree-5 minimax polynomial with maximum error under 1.3 * 2**-61.
- *   The values in exp2t[] and eps[] are chosen such that
- *   exp2t[i] = exp2(i/TBLSIZE + eps[i]), and eps[i] is a small offset such
- *   that exp2t[i] is accurate to 2**-64.
- *
- *   Note that the range of i is +-TBLSIZE/2, so we actually index the tables
- *   by i0 = i + TBLSIZE/2.  For cache efficiency, exp2t[] and eps[] are
- *   virtual tables, interleaved in the real table tbl[].
- *
- *   This method is due to Gal, with many details due to Gal and Bachelis:

- * exp2f(x): compute the base 2 exponential of x
- *
- * Accuracy: Peak error < 0.501 ulp; location of peak: -0.030110927.
- *
- * Method: (equally-spaced tables)
- *
- *   Reduce x:
- *     x = 2**k + y, for integer k and |y| <= 1/2.
- *     Thus we have exp2f(x) = 2**k * exp2(y).
- *
- *   Reduce y:
- *     y = i/TBLSIZE + z for integer i near y * TBLSIZE.
- *     Thus we have exp2(y) = exp2(i/TBLSIZE) * exp2(z),
- *     with |z| <= 2**-(TBLSIZE+1).
- *
- *   We compute exp2(i/TBLSIZE) via table lookup and exp2(z) via a
- *   degree-4 minimax polynomial with maximum error under 1.4 * 2**-33.
- *   Using double precision in the final calculation avoids roundoff error.
- *
- *   This method is due to Tang, but I do not use his suggested parameters:

-/* expm1(x)
- * Returns exp(x)-1, the exponential of x minus 1.
- *
- * Method
- *   1. Argument reduction:
- *	Given x, find r and integer k such that
- *
- *               x = k*ln2 + r,  |r| <= 0.5*ln2 ~ 0.34658
- *
- *      Here a correction term c will be computed to compensate
- *	the error in r when rounded to a floating-point number.
- *
- *   2. Approximating expm1(r) by a special rational function on
- *	the interval [0,0.34658]:
- *	Since
- *	    r*(exp(r)+1)/(exp(r)-1) = 2+ r^2/6 - r^4/360 + ...
- *	we define R1(r*r) by
- *	    r*(exp(r)+1)/(exp(r)-1) = 2+ r^2/6 * R1(r*r)
- *	That is,
- *	    R1(r**2) = 6/r *((exp(r)+1)/(exp(r)-1) - 2/r)
- *		     = 6/r * ( 1 + 2.0*(1/(exp(r)-1) - 1/r))
- *		     = 1 - r^2/60 + r^4/2520 - r^6/100800 + ...
- *      We use a special Reme algorithm on [0,0.347] to generate
- * 	a polynomial of degree 5 in r*r to approximate R1. The
- *	maximum error of this polynomial approximation is bounded
- *	by 2**-61. In other words,
- *	    R1(z) ~ 1.0 + Q1*z + Q2*z**2 + Q3*z**3 + Q4*z**4 + Q5*z**5
- *	where 	Q1  =  -1.6666666666666567384E-2,
- * 		Q2  =   3.9682539681370365873E-4,
- * 		Q3  =  -9.9206344733435987357E-6,
- * 		Q4  =   2.5051361420808517002E-7,
- * 		Q5  =  -6.2843505682382617102E-9;
- *  	(where z=r*r, and the values of Q1 to Q5 are listed below)
- *	with error bounded by
- *	    |                  5           |     -61
- *	    | 1.0+Q1*z+...+Q5*z   -  R1(z) | <= 2
- *	    |                              |
- *
- *	expm1(r) = exp(r)-1 is then computed by the following
- * 	specific way which minimize the accumulation rounding error:
- *			       2     3
- *			      r     r    [ 3 - (R1 + R1*r/2)  ]
- *	      expm1(r) = r + --- + --- * [--------------------]
- *		              2     2    [ 6 - r*(3 - R1*r/2) ]
- *
- *	To compensate the error in the argument reduction, we use
- *		expm1(r+c) = expm1(r) + c + expm1(r)*c
- *			   ~ expm1(r) + c + r*c
- *	Thus c+r*c will be added in as the correction terms for
- *	expm1(r+c). Now rearrange the term to avoid optimization
- * 	screw up:
- *		        (      2                                    2 )
- *		        ({  ( r    [ R1 -  (3 - R1*r/2) ]  )  }    r  )
- *	 expm1(r+c)~r - ({r*(--- * [--------------------]-c)-c} - --- )
- *	                ({  ( 2    [ 6 - r*(3 - R1*r/2) ]  )  }    2  )
- *                      (                                             )
- *
- *		   = r - E
- *   3. Scale back to obtain expm1(x):
- *	From step 1, we have
- *	   expm1(x) = either 2^k*[expm1(r)+1] - 1
- *		    = or     2^k*[expm1(r) + (1-2^-k)]
- *   4. Implementation notes:
- *	(A). To save one multiplication, we scale the coefficient Qi
- *	     to Qi*2^i, and replace z by (x^2)/2.
- *	(B). To achieve maximum accuracy, we compute expm1(x) by
- *	  (i)   if x < -56*ln2, return -1.0, (raise inexact if x!=inf)
- *	  (ii)  if k=0, return r-E
- *	  (iii) if k=-1, return 0.5*(r-E)-0.5
- *        (iv)	if k=1 if r < -0.25, return 2*((r+0.5)- E)
- *	       	       else	     return  1.0+2.0*(r-E);
- *	  (v)   if (k<-2||k>56) return 2^k(1-(E-r)) - 1 (or exp(x)-1)
- *	  (vi)  if k <= 20, return 2^k((1-2^-k)-(E-r)), else
- *	  (vii) return 2^k(1-((E+2^-k)-r))
- *
- * Special cases:
- *	expm1(INF) is INF, expm1(NaN) is NaN;
- *	expm1(-INF) is -1, and
- *	for finite argument, only expm1(0)=0 is exact.
- *
- * Accuracy:
- *	according to an error analysis, the error is always less than
- *	1 ulp (unit in the last place).
- *
- * Misc. info.
- *	For IEEE double
- *	    if x >  7.09782712893383973096e+02 then expm1(x) overflow
- *
- * Constants:
- * The hexadecimal values are the intended ones for the following
- * constants. The decimal values may be used, provided that the
- * compiler will convert from decimal to binary accurately enough
- * to produce the hexadecimal values shown.

-/* double log1p(double x)
- *
- * Method :
- *   1. Argument Reduction: find k and f such that
- *			1+x = 2^k * (1+f),
- *	   where  sqrt(2)/2 < 1+f < sqrt(2) .
- *
- *      Note. If k=0, then f=x is exact. However, if k!=0, then f
- *	may not be representable exactly. In that case, a correction
- *	term is need. Let u=1+x rounded. Let c = (1+x)-u, then
- *	log(1+x) - log(u) ~ c/u. Thus, we proceed to compute log(u),
- *	and add back the correction term c/u.
- *	(Note: when x > 2**53, one can simply return log(x))
- *
- *   2. Approximation of log1p(f).
- *	Let s = f/(2+f) ; based on log(1+f) = log(1+s) - log(1-s)
- *		 = 2s + 2/3 s**3 + 2/5 s**5 + .....,
- *	     	 = 2s + s*R
- *      We use a special Reme algorithm on [0,0.1716] to generate
- * 	a polynomial of degree 14 to approximate R The maximum error
- *	of this polynomial approximation is bounded by 2**-58.45. In
- *	other words,
- *		        2      4      6      8      10      12      14
- *	    R(z) ~ Lp1*s +Lp2*s +Lp3*s +Lp4*s +Lp5*s  +Lp6*s  +Lp7*s
- *  	(the values of Lp1 to Lp7 are listed in the program)
- *	and
- *	    |      2          14          |     -58.45
- *	    | Lp1*s +...+Lp7*s    -  R(z) | <= 2
- *	    |                             |
- *	Note that 2s = f - s*f = f - hfsq + s*hfsq, where hfsq = f*f/2.
- *	In order to guarantee error in log below 1ulp, we compute log
- *	by
- *		log1p(f) = f - (hfsq - s*(hfsq+R)).
- *
- *	3. Finally, log1p(x) = k*ln2 + log1p(f).
- *		 	     = k*ln2_hi+(f-(hfsq-(s*(hfsq+R)+k*ln2_lo)))
- *	   Here ln2 is split into two floating point number:
- *			ln2_hi + ln2_lo,
- *	   where n*ln2_hi is always exact for |n| < 2000.
- *
- * Special cases:
- *	log1p(x) is NaN with signal if x < -1 (including -INF) ;
- *	log1p(+INF) is +INF; log1p(-1) is -INF with signal;
- *	log1p(NaN) is that NaN with no signal.
- *
- * Accuracy:
- *	according to an error analysis, the error is always less than
- *	1 ulp (unit in the last place).
- *
- * Constants:
- * The hexadecimal values are the intended ones for the following
- * constants. The decimal values may be used, provided that the
- * compiler will convert from decimal to binary accurately enough
- * to produce the hexadecimal values shown.
- *
- * Note: Assuming log() return accurate answer, the following
- * 	 algorithm can be used to compute log1p(x) to within a few ULP:
- *
- *		u = 1+x;
- *		if(u==1.0) return x ; else
- *			   return log(u)*(x/(u-1.0));
- *
- *	 See HP-15C Advanced Functions Handbook, p.193.
