NAME

cproj, cprojf, cprojl − project into Riemann Sphere

SYNOPSIS

#include <complex.h>

double complex cproj(double complex z);
float complex cprojf(float complex
z);
long double complex cprojl(long double complex
z);

Link with −lm.

DESCRIPTION

This function projects a point in the plane onto the surface of a Riemann Sphere, the one-point compactification of the complex plane. Each finite point z projects to z itself. Every complex infinite value is projected to a single infinite value, namely to positive infinity on the real axis.

CONFORMING TO

C99

NOTE

The glibc implementation is broken and does something entirely different.
