[Python-ideas] division oddness

Shouldn't by by mathematical definition -x // y be the same as -(x // y)? But when assign x=2, y=3
you get:
>>> -2 // 3
-1
>>> -(2 // 3)
0
And also:
>>> 2 // -3
-1
>>> -2 // -3
0
And even more:
>>> int(-2 / 3)
0
>>> int(2 / -3)
0
I think this rather odd. Is there any deeper reason to this behaviour? I guess changing this will
break a lot of code, but why does it behave like this?
