Zachary Ware <zachary.w...@gmail.com> added the comment:

`operator` seems a slightly odd place for this.  My naive expectation would be 
that `float(floatlike_obj)` should do what you want, but it seems that's not 
the case (too permissive of input types?).  So then, what about an alternate 
constructor on the float object, `float.from_floatlike(obj)`?  This could be 
implemented as effectively:

class float:
    @classmethod
    def from_floatlike(cls, obj):
        return cls(PyFloat_FromDouble(PyFloat_AsDouble(obj)))

which would work to get an instance of any float subclass after a round-trip 
through a double.  I have no idea whether that's actually useful, though :)
