    > 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.

    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.

  • NTSC-CRT

    NTSC encoding/decoding in C89 using only integers and fixed point math. Supports NES decoding. Can be used as an image filter for games or real-time applications.

  • shine

    Super fast fixed-point MP3 encoder with JS/wasm and android native bindings.

    why not manky MP3 encoders too? toots/shine is particularly boggin.

  • fxpmath

    A python library for fractional fixed-point (base 2) arithmetic and binary manipulation with Numpy compatibility.

  • PL3D-KC

    A very fast and simple software renderer using only integers and fixed point math. PiSHi LE (PL) is a subset of the 3D software graphics library used in King's Crook.

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
