double complex conj(double complex z);

float complex conjf(float complex z);

long double complex conjl(long double complex z);

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)).

C99
