What the heck?? Is there any widely accepted industry standard for that "odd" rule? Why not round down half-integers whose cross total in hexagesimal representation has an odd number of prime divisors, and round up otherwise? </sarcasm> > On Python 3, when giving a non-zero argument for the second > argument--rounding to a decimal place--it always returns a float. > > Also on Python 3, an object a type that implements __round__ can > return any type it wants for round(obj). If I understand correctly, Sage currently uses .round() for customised rounding. Would it be a good idea to add a .__round__() method to sage.structure.element.Element that by default tries to return self.round()? In future, rounding should of course be implemented by overriding the default .__round__(), and old .round() should probably be renamed.
