## Lessons Learned

- Day 11

    - Even though an IEEE 754 32-bit floating point number has a max value of 3.40282347E+38, it can't properly represent all numbers above 2^24 (https://stackoverflow.com/a/23031245/9080819)

    - `as f32` will silently overflow, instead use `into`/`try_into`

- Day 13

    - Be careful using `str.lines().tuples()` when there's an empty line being discarded. The end of the file may not be completely read unless it has the proper newlines.
