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 

     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  max-
     imum 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.

ERORS
     No errors are defined.
