With the current coercion and number field model, I very strongly disagree -- the I should be symbolic. Anyway, you didn't give any argument for why you think "I" should be a number field element instead of a symbolic element. I would probably agree with you if you were to give a good argument for why you think that, and if number fields were much more sophisticated, and if the coercion model were suitably enhanced. > This doesn't resolve your second issue though, I think William's > simpify_complex is a good idea. OK. This would be very easy to add. william --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://sage.scipy.org/sage/ and http://modular.math.washington.edu/sage/ -~----------~----~----~----~------~----~------~--~---
