There are 2 more operations supported by `numpy` that are missing in the list above: 1. `multiply(duration, double/float) -> duration` 2. `divide(duration, double/float) -> duration` In both cases, `numpy` performs automatic rounding towards the specified time resolution: ```python import numpy as np td = np.timedelta64(5, "D") print(td * 1.5) # 7 days print(td / 1.5) # 3 days ``` Especially the multiply kernel would be very useful, because it is the inverse operation to the `divide(duration, duration) -> double` kernel, which is needed if one wants to reverse pre-processing transformations. -- This is an automated message from the Apache Git Service.
