PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (con-
       sult 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
       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.

ERRORS
       No errors are defined.
