[issue1512791] module wave does no rounding

[Mark Dickinson]

Mark Dickinson <dickinsm at gmail.com> added the comment:

I also meant to add that I left the int() call in, for slightly obscure reasons:  round doesn't currently return an int for all numeric types---it does for ints, floats and Decimal instances, but not for Fraction instances (arguably a defect of the fractions module, but that's another issue).  The 'int' doesn't seem like a huge extra cost, and it's conceivable that people might use Fraction for framerates, so it seemed safer to leave it in.
