(a) wait for sage-2.5 in which you get: sage: f = x - 3.3 sage: f x - 3.30000000000000 (b) Today: sage: x = polygen(RR,'x') sage: f = x - 3.3 sage: f 1.00000000000000*x - 3.30000000000000 --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to [email protected] 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/ -~----------~----~----~----~------~----~------~--~---
