Wrong! It's 0.30000000000000004. Getting JS to evaluate basic decimal math is a StackOverflow greasy rabbit hole of hacky solutions guaranteed to work for at least a week. JavaScript needs a 3rd-party 24KB library to accomplish basic decimal math(1), alternatively you can use the new (and not well supported) BigInt() to pretend you're doing decimal math by string hacking decimal points into super long integers.
