An arbitrary-precision arithmetic library for Rust.
Parts of Malachite are derived from GMP, FLINT, and MPFR.
The documentation for Malachite is here, and its crate is here.
Floats (arbitrary-precision floating-point numbers) are still in development and are not yet feature-complete, but the floating-point functions that are implemented are thoroughly tested and documented.
Malachite is developed by Mikhail Hogrefe.
