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.

NAME

       fmin, fminf, fminl — determine minimum numeric value of two floating-point numbers

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.1‐2008 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.
