fmin - Man Page

determine minimum numeric value of two floating-point numbers

Prolog

This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.

Synopsis

#include <math.h>

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

Description

The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of POSIX.1-2017 defers to the ISO C standard.

These functions shall determine the minimum numeric value of their arguments. NaN arguments shall be treated as missing data: if one argument is a NaN and the other numeric, then these functions shall choose the numeric value.

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.
