Yeah, I’m confused. “The Decimal Type<https://peps.python.org/pep-3141/#the-decimal-type>
After consultation with its authors it has been decided that the Decimal type should not at this time be made part of the numeric tower.” https://peps.python.org/pep-3141/#the-decimal-type And the Decimal definition I’m finding says: class Decimal(object): yet print(issubclass(Decimal,Number)) returns True.

On the other hand, Number is entirely abstract, so it doesn’t provide useful type checking for the implementation; I had to add # noinspection PyTypeChecker to 2 * value to keep PyCharm from complaining. Additionally, it does not include the Decimal type. Hmm...
