You could also use the is_integral method of rational numbers: sage: n = 3/2 + 1/2 sage: n.is_integral() True (This function also exists on Integers, so you could even use it in situations where you weren't sure if you had an honest Integer or an integer masquerading as a Rational.) -cc --~--~---------~--~----~------------~-------~--~----~ 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 -~----------~----~----~----~------~----~------~--~---
