It's Python's integer division at work...

>>> -1/100000L
-1L
>>> 1/100000L
0L
>>> -(1/100000L)
0L

Integer division rounds down to the nearest integer. For positive
numbers, this is unsurprising:

>>> 9/4
2

(2.25 -> 2), but negative numbers may not yield what you expected:

>>> -9/4
-3

-2.25 -> -3, because -3 is the first integer *lower* than -2.25.

I must admit, it does look strange to see things like -1/10 and
get -1 back.
