Line-by-line transliteration of the C math library, delivering comprehensive IEEE-compliant floating-point math functions with faithful behavior, port provenance headers, and in-progress feature-parity tracking.
This is a Kotlin Multiplatform line-by-line transliteration port of libm.
Original Project: This port is based on libm. All design credit and project intent belong to the upstream authors; this repository is a faithful port to Kotlin Multiplatform with no behavioural changes intended.
This is an in-progress port. The goal is feature parity with the upstream Rust crate while providing a native Kotlin Multiplatform API. Every Kotlin file carries a // port-lint: source <path> header naming its upstream Rust counterpart so the AST-distance tool can track provenance.

A Rust implementations of the C math library.
libm provides fallback implementations for Rust's float math functions in
core, and the core_float_math feature. If what is available suits your
needs, there is no need to add libm as a dependency.
If more functionality is needed, this crate can also be used directly:
[dependencies]
libm = "0.2.11"Please check CONTRIBUTING.md
This crate supports rustc 1.63 and newer.
