-FUNCTION
- <<cproj>>, <<cprojf>>--- Riemann sphere projection
-
-INDEX
- cproj
-INDEX
- cprojf
-
-ANSI_SYNOPSIS
- #include <complex.h>
- double complex cproj(double complex <[z]>);
- float complex cprojf(float complex <[z]>);
-
-
-DESCRIPTION
- These 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))
-
- <<cprojf>> is identical to <<cproj>>, except that it performs
- its calculations on <<floats complex>>.
-
-RETURNS
- The cproj functions return the value of the projection onto
- the Riemann sphere.
-
-PORTABILITY
- <<cproj>> and <<cprojf>> are ISO C99
-
-QUICKREF
- <<cproj>> and <<cprojf>> are ISO C99
