HP-UX Reference (11i v2 04/09) - 3 Library Functions A-M (vol 6)

conj(3M) conj(3M)

(Itanium(R)-based System Only)

NAME

conj( ), conjf( ), conjl( ), conjw( ), conjq( ) - complex conjugate functions

SYNOPSIS

#include <complex.h>

double complex conj(double complex z);

float complex conjf(float complex z);

long double complex conjl(long double complex z);

extended complex conjw(extended complex z);

quad complex conjq(quad complex z);

DESCRIPTION

These functions are available only for Itanium-based systems.

conj() returns the complex conjugate of z, computed by reversing the sign of its imaginary part.

conjf() is a float complex version of

conj(); it takes a float complex argument and returns a

float complex result.

conjl() is a long double complex version of conj(); it takes a long double complex

argu-

ment and returns a

long double complex result.

conjw() is an extended complex version of conj(); it takes an extended complex argument

and returns an extended complex result.

conjq() is equivalent to conjl() on HP-UX systems.

These functions raise no exceptions.

USAGE

To use these functions, compile with the default

-Ae option. To use conjw()

or conjq(), compile

with the

-fpwidetypes option. Make sure your program includes <complex.h>. Link in the math

library by specifying -lm on the compiler or linker command line.

ERRORS

No errors are deﬁned.
