I see. So rectform does the trick by pulling %i out.
And it probably works for any expression involving
elementary functions. Unfortunately this doesn't
seem like efficient method. And what about special
functions? The ultimate goal is numerical evaluation
of any expression involving any elementary and special
functions. For example, Maxima has the code for numerical
gamma function on complex plane (gamma-lanczos) but
it seems to be out of use.
