Line-by-line transliteration of a numeric traits library offering generic numeric traits (Float, Real, FloatCore, Pow, MulAdd), with provenance headers for AST-distance tracking and feature parity intent.
This is a Kotlin Multiplatform line-by-line transliteration port of num-traits.
Original Project: This port is based on num-traits. 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.
The text below is reproduced from
https://github.com/rust-num/num-traits. It is the upstream project's own description and remains under the upstream authors' authorship; links have been rewritten to absolute upstream URLs where appropriate so they continue to resolve from this repository.
Numeric traits for generic mathematics in Rust.
Add this to your Cargo.toml:
[dependencies]
num-traits = "0.2"This crate can be used without the standard library (#![no_std]) by disabling
the default std feature. Use this in Cargo.toml:
[dependencies.num-traits]
version = "0.2"
default-features = false
# features = ["libm"] # <--- Uncomment if you wish to use `Float` and `Real` without `std`The Float and Real traits are only available when either std or libm is enabled.
The libm feature is only available with Rust 1.31 and later (see PR #99).
The FloatCore trait is always available. MulAdd and MulAddAssign for f32
and f64 also require std or libm, as do implementations of signed and floating-
point exponents in Pow.
Implementations for i128 and u128 are only available with Rust 1.26 and
later. The build script automatically detects this, but you can make it
mandatory by enabling the i128 crate feature.
Release notes are available in RELEASES.md.
The num-traits crate is tested for rustc 1.8 and greater.
