Compute the projection of a complex number on the Riemann sphere

Synopsis:

#include <complex.h>

double complex cproj(double complex z);

float complex cprojf(float complex z);

long double complex cprojl(long double complex z);

Arguments:

z
The complex value that you want to get the projection of.

Library:

libm
The general-purpose math library.
libm-sve
(QNX Neutrino 7.1 or later) A library that optimizes the code for ARMv8.2 chips that have Scalable Vector Extension hardware.

Your system requirements will determine how you should work with these libraries:

Note: Compile your program with the -fno-builtin option to prevent the compiler from using a built-in version of the function.

Description:

These functions compute the projection of the complex number specified by z on the Riemann sphere.

Returns:

The projection of z on the Riemann sphere.

Classification:
