33 .\"O This function projects a point in the plane onto the surface of a
34 .\"O Riemann Sphere, the one-point compactification of the complex plane.
35 .\"O Each finite point
40 .\"O Every complex infinite value is projected to a single infinite value,
41 .\"O namely to positive infinity on the real axis.
