### [edit] Parameters

z | - | complex argument

### [edit] Return value

The projection of `z` on the Riemann sphere.

### [edit] Example

Run this code

    #include <stdio.h>
    #include <complex.h>
    #include <math.h>

    int main(void)
    {
        double complex z = cproj(INFINITY+2.0*I);
        printf("%.1f%+.1fi\n", creal(z),cimag(z));

        return 0;
    }

Output:

    inf+0.0i
