--- Comment #1 from Jacob Lifshay <programmerjake at gmail.com> ---
WIP algebraic numbers library at https://salsa.debian.org/Kazan-team/algebraics

-- represents values exactly
-- makes writing correctly rounded operations simple (as long as the operations
don't produce transcendental numbers)
-- has a quadratic number type that works for implementing add, sub, mul, div,
sqrt, rsqrt, fma
-- meant for testing since it's probably rather slow; still faster than python
would be
-- will be writing python bindings using https://pyo3.rs/v0.7.0/ which makes
writing bindings almost trivial
