What is 0.1 + 0.2 in JavaScript. I'll give you a hint, it's not 0.3. Is that fine?

That's not a JavaScript issue. It's the same for almost any language where you don't use some bignum type/library. This is something all developers should be extremely aware of.

To answer your question directly - yes, it’s fine, it’s actually expected behavior.
