Obtains the conjugate of a complex number

#include <complex.h>
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 of its complex argument. The conjugate of a complex number x + yi, where x and y are the real and imaginary parts, is defined as x - yi. Accordingly, the conj( ) function calculates the conjugate by changing the sign of the imaginary part.
