We should include failure case tests that are just outside the boundaries: -2147483649, 2147483648. And maybe some other "too long number" tests.

Might be good to also include expected failures that are legal floating point numbers such as "1.0", "1.", "1e1", ".1", "infinity". Some ways of implementing this might accidentally allow those.

We should include a failure case test that is just outside the boundary: 4294967296.
