Note that the selection of functions is similar, but not identical, to
that in module \code{math}. The reason for having two modules is,
that some users aren't interested in complex numbers, and perhaps
don't even know what they are. They would rather have \code{math.sqrt(-1)}
raise an exception than return a complex number. Also note that the
functions defined in \code{cmath} always return a complex number, even
if the answer can be expressed as a real number (in which case the
complex number has an imaginary part of zero).
