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. |
