NAME
cproj, cprojf, cprojl  project into Riemann Sphere
SYNOPSIS
#include
double complex cproj(double complex z);
float complex cprojf(float complex z);
long double complex cprojl(long double complex z);
Link with lm.
DESCRIPTION
This function projects a point in the plane onto the surface of a Rie
mann Sphere, the onepoint 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.
CONFORMING TO
C99.
NOTES
The glibc implementation is broken and does something entirely differ
ent.
