cproj, cprojf, cprojl
compute projection onto Riemann sphere

#include <complex.h>

double complex
cproj(double complex z);

float complex
cprojf(float complex z);

long double complex
cprojl(long double complex z);

The cproj(), cprojf() and cprojl() functions compute a projection of z onto the Riemann sphere.

The cproj(), cprojf() and cprojl() functions return z for all finite complex numbers. If z has an infinite part (even if the other part is NaN), they return the equivalent of:
INFINITY + I * copysign(0.0, cimag(z))

cimag(3)

The cproj(), cprojf() and cprojl() functions conform to ISO/IEC 9899:1999 (“ISO C99”).
