C in a Nutshell

Name

conj

Synopsis

Obtains the conjugate of a complex number

#include <complex.h>
double complexconj( 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.
