[edit] Parameters

z - complex argument

[edit] Return value

The complex conjugate of z.

[edit] Example

#include <stdio.h>
#include <complex.h>
 
int main(void)
{ 
    double complex z = conj(1.0 + 2.0*I);
    printf("%f%+fi\n", creal(z), cimag(z));
 
    return 0;
}

Output:

1.000000-2.000000i
