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 in development and are currently experimental. They are missing many important functions. However, the floating-point functions that are currently implemented are thoroughly tested and documented, with the exception of string conversion functions. The current floating-point string conversion functions are incomplete and will be changed in the future to match MPFR's behavior.
Malachite is developed by Mikhail Hogrefe.
