cproj is a standard C programming language function.
Used to compute complex projection functions.
The values which have to be projected are specified by z.
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.
The cproj() return the value of projection on Riemann sphere.
