NAME
fmin( ), fminf( ), fminl( ), fminw( ), fminq( ) - minimum value functions
SYNOPSIS
#include <math.h>
double fmin(double x, double y);
HP Integrity Server Only
float fminf(float x, float y);
long double fminl(long double x, long double y);
extended fminw(extended x, extended y);
quad fminq(quad x, quad y);
DESCRIPTION
The fmin() function determines the minimum numeric value of its arguments.
Integrity Server Only
fminf() is a float version of fmin(); it takes
float arguments and returns a float result.
fminl() is a long double version of fmin(); it takes long double arguments and returns a
long double result.
fminw() is an extended version of fmin(); it takes extended arguments and returns an
extended result.
fminq() is equivalent to fminl() on HP-UX systems.
USAGE
To use this function, compile either with the default
-Ae option or with the -Aa
and -D_HPUX_SOURCE
options. To use (for Integrity servers) fminw() or fminq(), compile with the -fpwidetypes
option.
Make sure your program includes
<math.h>. Link in the math library by specifying -lm on the com-
piler or linker command line.
RETURN VALUE
The
fmin() function returns the minimum numeric value of its arguments.
If one argument is a NaN and the other is numeric,
fmin() returns the numeric argument.
If both arguments are NaNs,
fmin() returns NaN.
ERRORS
No errors are defined.
