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.
