NAME

6       fmax,  fmaxf,  fmaxl - determine maximum numeric value of two floating-
7       point numbers
8

SYNOPSIS

10       #include <math.h>
11
12       double fmax(double x, double y);
13       float fmaxf(float x, float y);
14       long double fmaxl(long double x, long double y);

DESCRIPTION

18       These functions shall determine the  maximum  numeric  value  of  their
19       arguments. NaN arguments shall be treated as missing data: if one argu‐
20       ment is a NaN and the other numeric, then these functions shall  choose
21       the numeric value.
22

RETURN VALUE

24       Upon  successful  completion,  these functions shall return the maximum
25       numeric value of their arguments.
26
27       If just one argument is a NaN, the other argument shall be returned.
28
29       If x and y are NaN, a NaN shall be returned.
