-/* __ieee754_log10(x)
- * Return the base 10 logarithm of x
- * 
- * Method :
- *	Let log10_2hi = leading 40 bits of log10(2) and
- *	    log10_2lo = log10(2) - log10_2hi,
- *	    ivln10   = 1/log(10) rounded.
- *	Then
- *		n = ilogb(x), 
- *		if(n<0)  n = n+1;
- *		x = scalbn(x,-n);
- *		log10(x) := n*log10_2hi + (n*log10_2lo + ivln10*log(x))
- *
- * Note 1:
- *	To guarantee log10(10**n)=n, where 10**n is normal, the rounding 
- *	mode must set to Round-to-Nearest.
- * Note 2:
- *	[1/log(10)] rounded to 53 bits has error  .198   ulps;
- *	log10 is monotonic at all binary break points.
- *
- * Special cases:
- *	log10(x) is NaN with signal if x < 0; 
- *	log10(+INF) is +INF with no signal; log10(0) is -INF with signal;
- *	log10(NaN) is that NaN with no signal;
- *	log10(10**N) = N  for N=0,1,...,22.
- *
- * 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.
