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.
NOTE
The glibc implementation is broken and does something
entirely different.
