cproj, cprojf, cprojl

Retrieves the projection of a complex number on the Reimann sphere.


_Dcomplex cproj(   
   _Dcomplex z   
_Fcomplex cproj(   
   _Fcomplex z   
);  // C++ only  
_Lcomplex cproj(   
   _Lcomplex z   
);  // C++ only  
_Fcomplex cprojf(   
   _Fcomplex z   
_Lcomplex cprojl(   
   _Lcomplex z   


A complex number.

Return Value

The projection of z on the Reimann sphere.


Because C++ allows overloading, you can call overloads of cproj that take and return _Fcomplex and _Lcomplex values. In a C program, cproj always takes and returns a _Dcomplex value.
