There are pretty trivial ways to use binary floating point values that don't result in 0.1 + 0.2 producing 0.30000...4 and it saddens me when this topic comes up and people go to such extreme lengths to recreate a second hand buggy reimplementation of a subset of floating point numbers to do it.
That’s alright, the important part here is that they’re decimal, not binary. You don’t want 0.1 + 0.2 to equal 0.300…004.
