100% agree that picking numeric tolerances can be tricky. It is especially tricky when writing a generic math library like you are. If your doing something more applied it can help to take limits from your domain.
For the example in the blog, if you're using GPS to determine you're position on earth, you probably know how precise physics allows that answer to be, and you only need to test to that tolerance (or an order of magnitude more strict, to give some wiggle room.) |
