There’s plenty of cases where ‘==‘ is correct. If you understand how floating point numbers work at the same depth you understand integers, then you may know the result of each side and know there’s zero error.

Anything to do “approximately close” is much slower, prone to even more subtle bugs (often trading less immediate bugs for much harder to find and fix bugs).

For example, I routinely make unit tests with inputs designed so answers are perfectly representable, so tests do bit exact compares, to ensure algorithms work as designed.

I’d rather teach students there’s subtlety here with some tradeoffs.
