For example, in printf, you can use `%g` to use simple notation for small numbers and scientific notation for large numbers. There should be a way to do this in NumberFormatter. Ideas:

```
1
2
```

```
Notation.scientific().exceptWithinRange(1e-6, 1e6)
Notation.range(Notation.scientific(), 1e-6, Notation.simple(), 1e6, Notation.scientific())
```

We also need to define exactly what happens at the boundary. For example, if you say to use scientific notation above 1e6, and you ask us to format 999999 with 3 significant digits, do we use simple notation because the number is less than 1e6, or do we use scientific notation since the rounded value is at the threshold?
