It means integer part, i.e. the greatest integer ≤ x. For x in (0, 1), int x = 0 (since 0 < x < 1), so the limit from the right would be zero. On the other hand, since in (-1, 0) int x = -1 (because -1 < x < 0), so the limit from the left would go to +infinity.
 
It probably means interior. But from the context I understood it from, int X would mean interior set of x.

I have no idea what it implies in your function. My guess is that it means x takes values from 0 to 1 or it means all values of x.
