Comment(by glynn):
Replying to [comment:12 annakrat]:
> I attached the diff for this, I decided for floor(x+0.5) logic (but we
could use just floor if someone is against this). I would rather get some
approval from other developers for this.
The advantage of floor() is that it will produce identical results to the
existing implementation for positive values.
The main disadvantage of floor() is that minuscule rounding errors can
result in the wrong value, e.g. (CELL)floor(1.9999999) is 1 rather than 2.
