NAME

       fmax, fmaxf, fmaxl - determine maximum numeric value of two floating-point numbers

SYNOPSIS

       #include <math.h>

       double fmax(double x, double y);
       float fmaxf(float x, float y);
       long double fmaxl(long double x, long double y);

DESCRIPTION

       These  functions  shall  determine  the  maximum numeric value of their arguments. NaN arguments shall be
       treated as missing data: if one argument is a NaN and the  other  numeric,  then  these  functions  shall
       choose the numeric value.

RETURN VALUE

       Upon successful completion, these functions shall return the maximum numeric value of their arguments.

       If just one argument is a NaN, the other argument shall be returned.

       If x and y are NaN, a NaN shall be returned.
