Currently, round(), floor(), and ceil() on interval objects return intervals.
There is a patch up at #2899 that changes these functions to return integers (round-> "round the midpoint", floor -> largest integer below the bottom of the interval, etc.). I think the reasoning is that round(), floor, ceil, etc. should always return integers. What do people think? Should we close the ticket, or should we merge the patch (after possible rebasing). To illustrate: Currently: sage: R = RealIntervalField(100) sage: a = R(9.5, 11.3); a.str(style='brackets') '[9.5000000000000000000000000000000 .. 11.300000000000000710542735760101]' sage: floor(a).str(style='brackets') '[9.0000000000000000000000000000000 .. 11.000000000000000000000000000000]' Proposed: sage: floor(a) 9 Thanks, Jason -- Jason Grout --~--~---------~--~----~------------~-------~--~----~ 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 -~----------~----~----~----~------~----~------~--~---
