OK, that's definitely a bug. By the way, testing this in Ginac directly is useful, which anybody can do by typing ginsh on sage.math: wst...@sage:~$ ginsh ginsh - GiNaC Interactive Shell (ginac V1.4.1) ... > sqrt(2)^2; 2 I've added this to the wiki. --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
