NAME

conj, conjf, conjl - calculate the complex conjugate

LIBRARY

Math library (libm, -lm)

SYNOPSIS

bash

#include <complex.h>

bash

double complex conj(double complex \nz\n);\n
\nfloat complex conjf(float complex \nz\n);\n
\nlong double complex conjl(long double complex \nz\n);

DESCRIPTION

These functions return the complex conjugate value of z. That is the value obtained by changing the sign of the imaginary part.

One has:

bash

cabs(z) = csqrt(z * conj(z))
