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 compiler 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.

STANDARDS CONFORMANCE

fmin(), fminf(), fminl() : ISO/IEC C99 (including Annex F, ``IEC 60559 floating-point arithmetic'')
