Which inexact type, though? Do you get decimal.Decimal, float, or something else? How do you make that choice? And it's a critical choice to make. They're not just "inexact numbers". You can have an exact float (eg 7/2) or an inexact one, and same with Decimal. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
