* BUG: ensure np.median does not drop subclass for NaN result.Marten van Kerkwijk2021-09-141-0/+10
| | | | | | | | Currently, np.median is almost completely safe for subclasses, except if the result is NaN. In that case, it assumes the result is a scalar and substitutes a NaN with the right dtype. This PR fixes that, since subclasses like astropy's Quantity generally use array scalars to preserve subclass information such as the unit.

* TST: Make nanfunc test ignore overflow instead of xfailing testSebastian Berg2021-09-071-3/+1
| | | | | | This makes the test more precise, and I ran into having to broaden the xfails otherwise, because right now reduce-likes incorrectly faile to give floating point warnings (and I was fixing that).

| * API: Ensure np.vectorize outputs can be subclasses.Marten van Kerkwijk2021-06-261-1/+21
| | | | | | | | | | | | | | As is, this is true for the ufunc case, but not for the gufunc case, even if the underlying function does produce a subclass. Given the care taken to ensure inputs are kept as subclasses, this is almost certainly an oversight, which is here corrected.

* API: Delay string and number promotion deprecation/future warningSebastian Berg2021-06-041-2/+1
| | | | | | | | | | Unfortunately, this seems to cause some pain in pandas at least to circumvent the warning. Delaying may complicate the creation of ufuncs for strings, but otherwise should not be a big problem. We have to make sure that we can reimplement the change quickly though, it is an important change in my opinion.
