The problem is the Sage preparser turning integer literals into Sage integers, which the Swig/Quantlib interface doesn't understand. Here are some workarounds: Use "r" after the number to make it raw (not preparsed): sage: todaysDate = Date(6r,October,2001r) Explicitly cast to int: sage: todaysDate = Date(int(6),October,int(2001)) Turn of numerical literal preparsing: sage: Integer=int; RealNumber=float sage: todaysDate = Date(6,October,2001) --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@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-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
