cprojl(3m) [opensolaris man page]

cproj(3M)						  Mathematical Library Functions						 cproj(3M)

NAME
cproj, cprojf, cprojl - complex projection functions SYNOPSIS
c99 [ flag... ] file... -lm [ library... ] #include <complex.h> double complex cproj(double complex z); float complex cprojf(float complex z); long double complex cprojl(long double 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)) RETURN VALUES
These functions return the value of the projection onto the Riemann sphere. ERRORS
No errors are defined. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Interface Stability |Standard | +-----------------------------+-----------------------------+ |MT-Level |MT-Safe | +-----------------------------+-----------------------------+ SEE ALSO
carg(3M), cimag(3M), complex.h(3HEAD), conj(3M), creal(3M), attributes(5), standards(5) SunOS 5.11 12 Jul 2006 cproj(3M)
