NAME

12       fmin, fminf, fminl - determine minimum numeric value of  two  floating-
13       point numbers
14

SYNOPSIS

16       #include <math.h>
17
18       double fmin(double x, double y);
19       float fminf(float x, float y);
20       long double fminl(long double x, long double y);

DESCRIPTION

24       These  functions  shall  determine  the  minimum numeric value of their
25       arguments. NaN arguments shall be treated as missing data: if one argu‐
26       ment  is a NaN and the other numeric, then these functions shall choose
27       the numeric value.
28

RETURN VALUE

30       Upon successful completion, these functions shall  return  the  minimum
31       numeric value of their arguments.
32
33       If just one argument is a NaN, the other argument shall be returned.
34
35       If x and y are NaN, a NaN shall be returned.
