-Integer Literals are arbitrary precision integers until they are used together with a non-literal. In `var x = 1 - 2;`, for example, the value of `1 - 2` is `-1`, which is assigned to `x` and thus `x` receives the type `int8` -- the smallest type that contains `-1`, although the natural types of `1` and `2` are actually `uint8`.

 It is even possible to temporarily exceed the maximum of 256 bits as long as only integer literals are used for the computation: `var x = (0xffffffffffffffffffff * 0xffffffffffffffffffff) * 0;` Here, `x` will have the value `0` and thus the type `uint8`.
