So, please suggest terms to use for at least these two things:
- value certainty (ideally, not using "digits", but something that is
independent of unit and rendering)
We want to specify the "limits of (possible) variation" of a value, which would be tolerce ([[Engineering tolerance]])
E.g. the value of electrical resistances, capacitors, etc. are measured in Ω ± % or F ± %. We could also either use/allow/display absolute or relative values.
- output exactness (here, the number of digits is actually what we want to talk
about)
Everywhere in the realm of software development precision is used for this. Therefore also here the suggestion of precision was not that bad.
Perhaps we need additional distinctions, but I'm sure we at least need these two concepts.
