BTW I think the following might be relevant: sage: I = RealInterval(10.0, 10.0) sage: I [10.000000000000000 .. 10.000000000000000] sage: I**10000 [9.9999999999993908e9999 .. 1.0000000000000429e10000] I don't know exactly what this means, since I don't understand enough about the semantics of the constructor, but surely someone like Carl Witty would know. (and is this is a bug: sage: I**1000000000 [2.0985787164673874e323228496 .. +infinity] ???) david --~--~---------~--~----~------------~-------~--~----~ 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://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
