I don't understand your logic?? There are 500 values,
ie, 000 to 499, then there are 500 values in the top
half, ie, 500 to 999. The dividing point is *immediately*
before 500, ie, 499.999999999999999 (forever)

So if it starts with a 5 it absolutely must be in the
top half. There is no favoring, just accuracy.
