Number/digit: exactly none of (empty set as a subset of another set); in probability theory, "guaranteed impossible".

Distinct from "pisoi'au" in that non-empty null subsets can be 0% of their relevant supersets, but are not exactly none of it (which is what "pino" means).

- pisoi'au
*(comp!)* - almost none of/almost 0/almost never/almost certainly not/nearly nothing of (technical sense) but technically being non-empty or possible in theory (not impossible).
- pisu'esoi'au
*(comp!)* - digit/number: at most almost-none of (0%, taken as a fraction of a whole); the referent set is null and may even be empty.
