The Decimal class behaves differently from the builtin
integer and float classes when performing modulus and
integer division operations:

>>> decimal.Decimal("14") % decimal.Decimal("10)
Decimal("4")
>>> decimal.Decimal("-14") % decimal.Decimal("10")
Decimal("-4)
>>> 14 % 10
4
>>> -14 % 10
6

Similar behavior occurs with negative numbers with the
integer division operator //.

Should these behave the same way?
