It really depends on what kind of analog hardware you use. Not exactly like either. You would different causes for error: Thermal, inherent indeterminism of interactions, decay/drift of value over time, boundary breaches with values near extrema, etc.

The C++ standard committee has seen a paper on adding those to the language, as a library feature: https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2019/p00...
There's a kind-of-popular fixed-point-math library for the language:

and I'm sure they have received some attention in other languages.
