I totally get why it is a cause for concern when adding to an int, but I feel like floor division by a positive should be expected to return an integer "safe".

Reproducing code example:

import numpy as np
np.uint64(0) // 4 
Out[2]: -0.0

I guess since I need to divide by 4 I'll just bitshift, but this was kinda unexpected for me.

Numpy/Python version information:

In [3]: import sys, numpy; print(numpy.__version__, sys.version)
