With insolvable i meant just the technical restrictions of floating point numbers. There are of course solutions. But there is just the fact that binary numbers with discrete length can only be mapped to so many numbers.

If you use numbers directly in exponential form in vanilla javascript, you already get better results.

It's not that they're not solvable, it's just that you have to go out of your way to use the proper type or library. The default floating point type still has problems.

Important caveat: BigDecimal is arbitrary-precision, not infinite-precision. Using it still requires you to think about the precision of each number you operate on.
