Hello, is there some multiplatform library to consistently represent floating-point numbers across all platforms? I'm working on "replay" system for my game, and I really need numbers to be consistent across platforms, but with default Float it fails on JS, where I can't even do Float.fromBits((-1e11f).toRawBits()) without getting distorted results

Kotlin/JS Float is a bit of a lie, it behaves like a Double (it's backed by JS Number either way)

val f = -1e11f // clamped to Float range at compile time, is -99999997952f on all platforms
val g = -1e11f.toFloat() // does't actually clamp to Float range at runtime on JS
f != g

Would Double work?

it should, there might be some inconsistencies around NaN but I expect other numbers will be fine
