Hi Tim,

For some reason decimal implemented mod as the proposed standard's "remainder" operation. That's the immediate source of your surprise. IMO decimal should not have implemented mod at all, as Python's number-theoretic mod is not part of the proposed standard, is a poor basis for a floating-point mod regardess, and it was a mistake to implement decimal % decimal in a way so visibly different from float % float and integer % integer: it confuses the meaning of "%". That's your complaint, right?

Thanks for the clarification. Yes, it makes sense that mod, divmod and floordiv on float and decimal would eventually follow the same path as for complex (where they make even less sense and already raise a DeprecationWarning).

A bientot,

Armin.
