Right, I am using Python 3. I did not know that the round behavior had changed because I have never been using Python 2.

>>> round(1.5)

The NumPy floats behave just like ordinary Python floats, until it gets to rounding. This had caused a hard-to-find bug in my project.

We changed float scalar rounding a while ago to align with Python (although not quite sure which NumPy version).
