FUNCTION
<<fmax>>, <<fmaxf>>---maximum
INDEX
fmax
INDEX
fmaxf
ANSI_SYNOPSIS
#include <math.h>
double fmax(double <[x]>, double <[y]>);
float fmaxf(float <[x]>, float <[y]>);
DESCRIPTION
The <<fmax>> functions determine the maximum numeric value of their arguments.
NaN arguments are treated as missing data: if one argument is a NaN and the
other numeric, then the <<fmax>> functions choose the numeric value.
RETURNS
The <<fmax>> functions return the maximum numeric value of their arguments.
PORTABILITY
ANSI C, POSIX.
