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.
