  #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))
