| 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. |
