Is there a particular reason why you updated the provided test here?

Can you think of how these test that expect throw can be made more robust?

Can you spot another test that checks the same thing here?

Nice idea to test decimals close to the boundary! Is there a particular reason to replace 89 rather than keep both values?

Good job! Very clean implementations and thorough test coverage, especially around the boundaries. Apart from a couple of small issues with the provided tests and formatting - everything looks solid! |
