fmaxf

fmax(3M)						  Mathematical Library Functions						  fmax(3M)

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.
