This fixes an issue with calling ufuncs with mixed args including upcast types: Calling a bivariate ufunc like np.maximum(da, 0 * ureg.m) resulted in pint trying to work with upcast types because __array_ufunc__ works with type objects while is_upcast_type checked object instances.

  • Executed black -t py36 . && isort -rc . && flake8 with no errors
  • The change is fully covered by automated unit tests

Thanks for catching this!

I have one comment below and a question: would you want to add tests for this now, or wait for the ones outlined in #845?

I think the tests should go to a PR for #845.

951: ufunc calls with mixed args and upcast types r=hgrecco a=keewis

This fixes an issue with calling ufuncs with mixed args including upcast types: Calling a bivariate ufunc like `np.maximum(da, 0 * ureg.m)` resulted in `pint` trying to work with upcast types because `__array_ufunc__` works with type objects while `is_upcast_type` checked object instances.

- [x] Executed ``black -t py36 . && isort -rc . && flake8`` with no errors
- [ ] The change is fully covered by automated unit tests
