Well, it is a *bit* of a Python issue since, as others have pointed out, Python's behavior has changed due to the implementation of Gay's rounding algorithm in 3.1 and also in 2.7: $ python2.6 -c 'print(repr(34.52))' 34.520000000000003 $ python2.7 -c 'print(repr(34.52))' 34.52 $ python3.1 -c 'print(repr(34.52))' 34.52 -- Ned Deily, n...@acm.org -- http://mail.python.org/mailman/listinfo/python-list
