rescale stopped working for rad and deg

[axelande]

Something broke in version 0.14.0 with regards to rescale:
In version 0.13.0:

heading = pq.Quantity(10, pq.deg)
print(heading.rescale(pq.rad)) -> array(0.17453293) * rad

In version 0.14.0:

heading = pq.Quantity(10, pq.deg)
heading.rescale(pq.rad) -> array(0) * rad

I can't see anything in changed api in the changelog?

Thanks for reporting this. We'll look into it urgently.

As a workaround, I note that explicitly giving heading a float dtype avoids the problem, e.g.

heading = pq.Quantity(10.0, pq.deg)
print(heading.rescale(pq.rad)) -> array(0.17453293) * rad

@bjodah could you look at this?

@apdavison, sure I'll look into this right away, I think I see what's happening here: numpy casting rules aren't really well suited for integer types in quantities. I'll try to put a PR together.

Many thanks for the quick response @bjodah !

@axelande I've made a bug-fix release. Updating to 0.14.1 should fix the problem.
