Describe your change:

  • Per comment on Added Continued fractions #6846, I've added doctests to continued_fractions.py for 0 and negative numbers
  • Fixed the implementation to work for negative numbers by replacing int() call with floor(): the algorithm requires a rounding down to the nearest int, but int() rounds to 0, not down
  • Add an algorithm?
  • Fix a bug or typo in an existing algorithm?
  • Documentation change?
