[issue7628] round() doesn't work correctly in 3.1.1

[Tim Peters]

Tim Peters <tim.peters at gmail.com> added the comment:

Note that round() is implemented much more carefully in Python 3.x than in Python 2.x, and 120 is actually the correct result under nearest/even rounding (125 is exactly halfway between representable values when rounded to the closest 10, and nearest/even rounding resolves the ambiguity by picking the closest value whose last relevant digit is even).
