Hello Mike, thank you for the quick response. This doesn't seem to fully work when querying the value using session.query(MyObject.my_hybrid_expression).scalar(). From the callstack, the Numeric (possibly representing the result of the multiplication) now seems to be initialized by type_api.py:to_instance, which calls the Numeric constructor without passing any **kwargs, so it again defaults to asdecimal=True. This method is called by sqltypes.py:_DateAffinity.Comparator._adapt_expression, which finds MyFloat._type_affinity == Numeric.
