Comment(by charris):

 I suspect this is another case of the 2 being treated as signed, hence the
 promotion to float64, which has insufficient precision. This also shows up
 in the shift operators, but there things are (were) promoted to objects.
 These ufuncs probably need special treatment of their arguments.
