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.
