Agreed that this seems surprising.

@Vedran: Trailing zeros in a Decimal object are significant, so `Decimal("2.0")` and `Decimal("2.00")` are different (equal, but different). The rules about the "ideal exponent" of the result of an arithmetic operation are well-specified. In this case, the spec is clear that the answer should be `Decimal("2")`, and not `Decimal("2.0")` or `Decimal("2.00")`, or ....
