Correction: Bitcoin is 8-digit fixed-point. But Lightning is 10, IIRC. Other currencies have different conventions. Still, it's fixed within a given system and always fixed-point. As far as I'm aware, there are no floating-point cryptocurrencies at all, because it would be an obvious exploit vector - keep withdrawing 0.000000001 units from your account that has 1.0 units.
