C++ header-only fixed-point math library (by MikeLankamp)

> more like a floating point ... or more like a fixed-point ... ?
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.
> IMO it is surprising fixed-point values don’t come up more often
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.

NeuralNetworks

1 62 8.1 C++

A resource-conscious neural network implementation for MCUs (by GiorgosXou)

Project mention: Is there anything like Embedded Artificial Intelligence & Machine Learning? Can anyone tell me more about it? | /r/embedded | 2023-12-07

Here's a resource-efficient Neural-Network library that I made1 specifically for MCUs, which I think you will find pretty interesting. Here's a simple xor-circuit NN example and here's a more advanced NN that predicts handwritten digits2 on an arduino UNO. Those combined with this research, I believe that will answer many of your questions and get you started.
