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
Every complex infinite value is projected to a single infinite value,
namely to positive infinity on the real axis.
These functions first appeared in glibc in version 2.1.
Multithreading (see pthreads(7))
functions are thread-safe.
In glibc 2.11 and earlier, the implementation does something different
