almost: A crate for comparing floating point numbers.

Docs

This crate strives to make choices that are good for most cases, and not providing you a complex API that encourages misuse.

  1. Uses relative comparison by default.
  2. Provides a separate function for comparison with zero (the only time when absolute comparison is a good default choice).
  3. Uses a better default for tolerance than std::{f32,f64}::EPSILON.
  4. Handles infinities / subnormals properly.
  5. no_std compatible always
