C Programming/complex.h/cproj

cproj is a standard C programming language function.

Purpose
Used to compute complex projection functions.

Parameters
The values which have to be projected are specified by z.

Description
This is complex projection functions. these are available for integrity servers. The projection of complex floating point-number z onto the Riemann sphere is done by cproj. But all complex infinities are projected to positive infinity on the real axis.

Return value
The cproj return the value of projection on Riemann sphere.
