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.
