Indeed! And since this is Cython code, I *guess* that I should combine `//` with the 'cdivision' set to True to get the syntax that everyone understands *and* the pure C speed (see http://cython.readthedocs.io/en/latest/src/reference/compilation.html). I need to run some experiments to make sure that this behaves as expected, but this is very likely the way to go.
