cprojl

SYNOPSIS
       #include <complex.h>

       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 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.

CONFORMING TO
       C99.

NOTES
       The  glibc implementation is broken and does something entirely differ-
       ent.
