+.Sh NAME
+.Nm fmax ,
+.Nm fmaxf ,
+.Nm fmaxl ,
+.Nm fmin ,
+.Nm fminf ,
+.Nm fminl
+.Nd floating-point maximum and minimum functions
+.Sh LIBRARY
+.Lb libm
+.Sh SYNOPSIS
+.In math.h
+.Ft double
+.Fn fmax "double x" "double y"
+.Ft float
+.Fn fmaxf "float x" "float y"
+.Ft "long double"
+.Fn fmaxl "long double x" "long double y"
+.Ft double
+.Fn fmin "double x" "double y"
+.Ft float
+.Fn fminf "float x" "float y"
+.Ft "long double"
+.Fn fminl "long double x" "long double y"
+.Sh DESCRIPTION
+The
+.Fn fmax ,
+.Fn fmaxf ,
+and
+.Fn fmaxl
+functions return the larger of
+.Fa x
+and
+.Fa y ,
+and likewise, the
+.Fn fmin ,
+.Fn fminf ,
+and
+.Fn fminl
+functions return the smaller of
+.Fa x
+and
+.Fa y .
+They treat
+.Li +0.0
+as being larger than
+.Li -0.0 .
+If one argument is an \*(Na, then the other argument is returned.
+If both arguments are \*(Nas, then the result is an \*(Na.
+These routines do not raise any floating-point exceptions.

+.Sh STANDARDS
+The
+.Fn fmax ,
+.Fn fmaxf ,
+.Fn fmaxl ,
+.Fn fmin ,
+.Fn fminf ,
+and
+.Fn fminl
+functions conform to
+.St -isoC-99 .
+.Sh HISTORY
+These routines first appeared in
+.Fx 5.3 .
