cprojf (3)
NAME
cproj, cprojf, cprojl - project into Riemann SphereSYNOPSIS
#include <complex.h> double complex cproj(double complex z);DESCRIPTION
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.VERSIONS
These functions first appeared in glibc in version 2.1.ATTRIBUTES
