How Mob ACC works

Another way to think of "floor" would be to round down. Always round down.

This is different from typecasting "int", though. "int" rounds toward zero whereas floor rounds down. That makes truncation different for values below zero. For the purposes of this calculation, though, floor and typecasting int do the same thing.

That depends on your language, in Python 2.6.5, int(-1.5) will give you -1 (tried just now).
