Other Alias

fminf, fminl

SYNOPSIS

#include <math.h>

double fmin(double x, double y);
float fminf(float x, float y);

RETURN VALUE

Upon successful completion, these functions shall return the minimum numeric value of their arguments.

If just one argument is a NaN, the other argument shall be returned.

If x and y are NaN, a NaN shall be returned.
