Implementation status: to be implemented
double complex cproj(double complex z);
float complex cprojf(float complex z);
long double complex cprojl(long double complex z);
The functions compute a projection of z onto the Riemann sphere: z projects to z, except that all complex infinities (even those with one infinite part and one
NaN part) project to positive infinity on the real axis. If z has an infinite part, then
cproj(z) is equivalent to:
INFINITY + I * copysign(0.0, cimag(z))
These functions return the value of the projection onto the Riemann sphere.
No errors are defined.
- Implement the functions: cproj(), cprojf() and cprojl(),
