 The Number type has only one value with multiple representations: `0` is represented as both `-0` and `+0` (where `0` is an alias for `+0`). In practice, there is almost no difference between the different representations; for example, `+0 === -0` is `true`. However, you are able to notice this when you divide by zero:
