-------- 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. Best wishes
