What is does is explained quiet quickly : It expands and factorizes (some) math expressions. You can download it here: http://www.dhost.info/voodoocpp/index.php?page=progs/progs Any comments welcome. Please report bugs (crashes, things you think that should have been expanded / factored) -------------------- Conscience doesn't really keep you from doing anything wrong -- it merely keeps you from enjoying it.

Thanks for the feedback.

Well what should it do else?

Isn't (x, lim(x->0)of(1/x)) then the point on the opposite side of the cylinder meaning (0, pir+2kpi) with k in Z. To come back to 1/x in the standard plan one would only have to let r go against +inf as a line is only a circle with infinite radius. It seems to work as lim (r->+inf) of (0, pir+2kpi) is (0, -inf) when k < 0 and (0, +inf) when k >= 0. -------------------- Conscience doesn't really keep you from doing anything wrong -- it merely keeps you from enjoying it.
