I've noticed the following strange behavior (bug): sage: A.<a> = PolynomialRing(QQ) sage: 3 in A True
sage: A2.<a,b> = PolynomialRing(QQ) sage: 3 in A2 False So apparently "in" for multivariate polynomial rings is slightly broken, but I don't know where to look to fix it. I did spend some time looking for documentation or previous email threads, but "in" makes for a tough search. (This seems to be called "membership testing" sometimes, but I haven't found documentation for that either.) thanks, Niles -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
