conj, conjf, conjl − calculate the complex conjugate
Math library (libm, −lm)
#include <complex.h>
double
complex conj(double complex z);
float complex conjf(float complex z);
long double complex conjl(long double complex
z);
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))
