Symbolic expressions keep python objects for numeric values or coefficients. You can get at the python object wrapped by an expression using the .pyobject() method and ask for its parent. sage: t = Mod(3,5) sage: t.parent() Ring of integers modulo 5 sage: u = SR(t) sage: u 3 sage: u.parent() Symbolic Ring sage: u.pyobject().parent() Ring of integers modulo 5 Cheers, Burcin --~--~---------~--~----~------------~-------~--~----~ 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 -~----------~----~----~----~------~----~------~--~---
