Martin, As you may or may not know the 'r' in your input below is supposed to stand for radix. So '2r...' indicates an integer written in base 2 notation. 8r would be octal notation etc. This works in OpenAxiom: wsp...@debian:~$ open-axiom -nox GCL (GNU Common Lisp) 2.6.7 CLtL1Sep 1 2008 14:01:57 Source License: LGPL(gcl,gmp), GPL(unexec,bfd,xgcl) Binary License: GPL due to GPL'ed components: (XGCL READLINE BFD UNEXEC) Modifications of this banner must retain notice of a compatible license Dedicated to the memory of W.

My 2r was a typo, I wanted to type 2*r. I just checked OpenAxiom, it gives 0 for 2r*x I'd vote for turning this feature off in FriCAS altogether (and replace it by something less error prone)!

http://www.aldor.org/docs/HTML/chap5.html#2 '2r' should give a syntax error if neither 0 or 1 is following.

I'd hope for an error. r is a variable name I use often, and at times I miss the multiplication sign.

I'll fix that tonight. Except that, I don't think integer literals expressed in radix other than 10 are dangerous at all. -- Gaby --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups FriCAS - computer algebra system group.
