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);


DESCRIPTION
       With  this function you can project a point in the plane onto the sur-
       face of a Riemann Sphere, the one-point compactification of  the	 com-
       plex  plane.  Each finite point z projects to z itself.	Every complex
       infinite values is projected to a single	 infinite  value,  namely  to
       positive infinity on the real axis.
