    Bechmarks for Rust big integer implementations

  • Have you performed benchmarks for this? I imagine it would be nice to have something similar to the big integer benchmarks provided by ibig.

  • ibig-rs

    A big integer library in Rust with good performance.

    Optimize floating-point expressions for accuracy

  • On a related note, see tools like Herbie which rewrite floating point expressions to improve accuracy without altering the underlying data-type. It's worth being aware that sometimes you get really bad diminishing returns from using bigger floats and what you really need to do is to rewrite the calculation to avoid a weakness of floating point representation, see numerically unstable calculations.

  • Clippy

    A bunch of lints to catch common mistakes and improve your Rust code. Book: https://doc.rust-lang.org/clippy/

  • It would be interesting to see something like Herbie in clippy https://github.com/rust-lang/rust-clippy/issues/346
