conj, conjf, conjl − calculate the complex conjugate
#include <complex.h>

complex conj(double complex z);
float complex conjf(float complex z);
long double complex conjl(long double complex
z);
Link with −lm.
The conj() function returns 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))
These functions first appeared in glibc in version 2.1.
Multithreading
(see pthreads(7))
The conj(), conjf(), and conjl()
functions are thread-safe.
