-------- Original Message -------- Subject: Problems with expand() Date: Thu, 28 Feb 2002 11:48:50 +0100 From: Tatiana Zolo <zolo@cs.unipr.it> Reply-To: ginac-list@zino.physik.uni-mainz.de To: ginac <ginac-list@zino.physik.uni-mainz.de> We have a few questions about GinaC's behaviour. For our purposes, it would be useful to have a slightly more general form of expand that takes care of non-ambiguous iterated exponentials, as in the case (2^x)^3 which we would like to see in the form 2^(3*x) or even 8^x We understand that there are cases when this should not be done automatically, but we believe that this is an instance when there is no harm in simplifying since 2 is a positive real number and there is no question of complex numbers being involved. A "real" version of expand would be very useful for us. Do you plan to add these features to a future release of GiNaC? Thank you very much.
