needs to be sorted out why it fails on ARM.
as far as floating point goes, 119.99999999999997 is definitely equal to
120...
I don't see why this can be classified as a bug. To me, it's just a
feature of this particular FPU, nothing
more than that. (e.g. it can present 6 as 5.9999999999999, nothing is
wrong with this...)
I think you can just modify the doctests accordingly.
Regarding the pickling, is this even a stable failure, i.e. when you re-
run this particular test, do you see exactly the same error
again and again?
