CPROJ(3)		  OpenBSD Programmer's Manual		      CPROJ(3)

NAME
     cproj, cprojf - compute projection onto Riemann sphere

SYNOPSIS
     #include <complex.h>

     double complex
     cproj(double complex z);

     float complex
     cprojf(float complex z);

DESCRIPTION
     The cproj() and cprojf() functions compute a projection of z onto the
     Riemann sphere.

RETURN VALUES
     The cproj() and cprojf() 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))

SEE ALSO
     cimag(3)

STANDARDS
     The cproj() and cprojf() functions conform to ISO/IEC 9899:1999 (``ISO
     C99'').
