Stefan Krah added the comment: Agreed, and it's even slightly worse with the ROUND_FLOOR special case: >>> c.rounding = ROUND_FLOOR >>> +Decimal("-0") Decimal('-0') >>> That's why there are three slightly different methods for applying the context: 1) context.create_decimal() ==>

Mark Dickinson added the comment: I agree that the result is surprising and should be noted in the docs; we shouldn't expect all the decimal users to be familiar with the specification. Some of the other differences with float arithmetic *are* noted (e.g., the behaviour of `//` and `%`),

New submission from JD-Veiga : Hi, I would like to propose a minor addition to `decimal` package documentation page (https://docs.python.org/3/library/decimal.html). I think that we should add a paragraph in `context.power(x, y, modulo=None)` stating that `Decimal(0) ** Decimal(0)` returns
