cproj, cprojf,
cprojl —
#include <complex.h>
double complex
cproj(double
complex z);
float complex
cprojf(float
complex z);
long double complex
cprojl(long
double complex z);
cproj(), cprojf() and
cprojl() functions compute a projection of
z onto the Riemann sphere.
cproj(), cprojf() and
cprojl() functions return z for
all finite complex numbers. If z has an infinite part
(even if the other part is NaN), they return the equivalent of:
INFINITY + I * copysign(0.0, cimag(z))
cproj(), cprojf() and
cprojl() functions conform to ISO/IEC
9899:1999 (“ISO C99”).
