NAME
conj, conjf, conjl - calculate the complex conjugate
LIBRARY
Math library (libm, -lm)
SYNOPSIS
#include <complex.h>
double complex conj(double complex z); float complex conjf(float complex z); long double complex conjl(long double complex z);
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:
cabs(z) = csqrt(z * conj(z))
