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

SYNOPSIS
       c99 [ flag... ] file... -lm [ library... ]
       #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 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, these functions choose the numeric value.

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

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

       If x and y are NaN, a NaN is returned.

ERRORS
       No errors are defined.
