If we consider it a bug, we could patch it in 1.16.1 (or are we still waiting on 1.16.0?), which would minimize the backwards compatibility cost. Eric On Tue, 8 Jan 2019 at 10:05 Stefan van der Walt wrote: > On Tue, 08 Jan 2019 09:57:03 -0800, Tyler Reddy wrote: > > np.timedelta64(5) % np.timed

I would say this is desirable behaviour, but I’m still +0.8 on this for backward compatibility reasons. I doubt anyone would build code that relies on this though… They would almost certainly check for the zero in the denominator rather than the return value. Best Regards, Hameer Abbasi > On T

2019-01-08 Thread Tyler Reddy
We are now at the stage of implementing the timedelta64 divmod inner loop given very recent additions of floordiv and remainder inner loops for this data type. However, there is some contention about a previous decision regarding modulus behavior that we'd like to resolve before we bake it in to di
