NAMEcproj, cprojf, cprojl - project into Riemann Sphere
double complex cproj(double complex z);
float complex cprojf(float complex z);
long double complex cprojl(long double complex z);
DESCRIPTIONThis 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.
VERSIONSThese functions first appeared in glibc in version 2.1.
NOTESThe glibc implementation is broken and does something entirely different.
