    NAME

    cproj, cprojf, cprojl - project into Riemann Sphere
     
    

    SYNOPSIS

    #include <complex.h>

    double complex cproj(double complex z);
    float complex cprojf(float complex z);
    long double complex cprojl(long double complex z);

    Link with -lm.  

    DESCRIPTION

    This function projects a point in the plane onto the surface of a Riemann Sphere, the one-point compactification of the complex plane. Each finite point z projects to z itself. Every complex infinite value is projected to a single infinite value, namely to positive infinity on the real axis.  

    VERSIONS

    These functions first appeared in glibc in version 2.1.  

    CONFORMING TO

    C99.  

    NOTES

    The glibc implementation is broken and does something entirely different.
