Yes. You've found a bug. That the following simple example doesn't work is a bug in Martin Albrecht's new incredibly fast multivariate polynomial arithmetic code: sage: R.<x,y,z> = GF(3)[] sage: R(1/2) Traceback (most recent call last): ... TypeError: Cannot convert sage.rings.integer_mod.IntegerMod_int to sage.rings.rational.Rational I'm sure Martin will fix it very soon. -- William --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@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-support URLs: http://sage.math.washington.edu/sage/ and http://sage.scipy.org/sage/ -~----------~----~----~----~------~----~------~--~---
