FUNCTION
<<fmin>>, <<fminf>>---minimum
INDEX
fmin
INDEX
fminf
ANSI_SYNOPSIS
#include <math.h>
double fmin(double <[x]>, double <[y]>);
float fminf(float <[x]>, float <[y]>);
DESCRIPTION
The <<fmin>> functions determine the minimum numeric value of their arguments.
NaN arguments are treated as missing data: if one argument is a NaN and the
other numeric, then the <<fmin>> functions choose the numeric value.
RETURNS
The <<fmin>> functions return the minimum numeric value of their arguments.
PORTABILITY
ANSI C, POSIX.
