Overview
Let a,+,b,*i denote the complex number z.
The creal() functions return the real part a, and the cimag() functions return the imaginary part b.
The conj() functions return the complex conjugate a,-,b,*i.
The cproj() functions return the projection onto the Riemann sphere. If z contains an infinite component, then the result is 0*i, where the (zero) imaginary part of the result has the same sign as b. Otherwise, the result is z.
These functions do not signal any floating point exceptions.
