These functions project 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.
For an explanation of the terms used in this section, see attributes(7).

In glibc 2.11 and earlier, the implementation does
something different (a stereographic projection onto a Riemann
Sphere).
