cproj, cprojf, cprojl - project into Riemann SphereSYNOPSIS

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
