That "undefined" gives implementations the freedom to use bigger representations if convenient.
Personally, my rule of thumb is this: Int = some number Integer = some *big* number Int32 (or whatever) = I actually want it exactly THIS size. So I just use Int when I don't really care what size the integer is - mainly becuase *everything* seems to use Int and it saves on explicit type conversions all over the place. (I'm not actually too sure that Int *should* be used all over the place - but it'll never be changed, so...)
