In 3.0, round() of a Decimal should return an int if invoked with 1 arg, a Decimal if invoked with 2. Similar for round() of a float. round() of an int can always return an int. In 2.6, round() should always return a float, regardless of the type of the first arg or the arg count, for best compatibility with 2.5. -- --Guido van Rossum (home page: http://www.python.org/~guido/) _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
