Tbh, the only practical non-integers we all need (apart from science-ish pretence and graphics) are .00, .000, .0000 and .000000 decimals (money, qty, percent.00, milliqty). Literally all business and in-game accounting needs get covered by these. Even edge/rounding issues are irrelevant, because everyone is ready to just agree to either way of doing it, and that agreement is much more important than the method itself. This floating bullshit is basically of none, zero, nil practical use outside of academics. Modern CPUs can effectively emulate whole subroutines in microcode, but somehow we got stuck with that useless binary floating point standard for numbers. And on top of that, languages provide them as a default numeric system for all new software.
