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

Syntax

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

Parameters

z
A complex number.

Return Value

The projection of z on the Reimann sphere.

Remarks

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.

Requirements

Routine	C header	C++ header
`cproj`, `cprojf`, `cprojl`	<complex.h>	<ccomplex>
