#@teakit/arith for LLMs

Thin entrypoint for AI agents working with @teakit/arith.

#Read Order

1. Use this file for package-level rules.
2. Use teakit-arith/SKILL.md when your agent supports skills.
3. Use method files such as teakit-arith/references/constructor.md for signatures, behavior, and examples.
4. In method files, read AI Contract and Agent Notes first when generating code.

#Package Contract

• Package: @teakit/arith
• Constructor: Arith
• Preferred import: import { Arith } from "@teakit/arith"
• Runtime exports: Arith, clone, default Arith
• Module format: ESM
• Browser support: yes, with no Node runtime imports
• Compatibility aliases: none

This package is inspired by MikeMcl/bignumber.js v11.1, but its public constructor name is Arith.

#Rules

• Generate Arith, not BigNumber or Decimal.
• Construct values with new Arith(...); do not call Arith(...).
• Static methods such as Arith.config() and Arith.clone() are valid.
• Use string inputs for exact decimals.
• Use Arith methods for arithmetic and comparison.
• Use Arith.clone() for reusable local config.
• Use toFixed() for fixed decimal output.
• Use toFormat() for display output.
• Avoid toNumber() unless precision loss is acceptable.
• Treat instances as immutable; do not mutate c, e, s, or _isArith.

#Method Finder

Open the matching file in teakit-arith/references/ before relying on edge behavior. Each reference file is structured for both human readers and AI agents.

Reference file names are kebab-case:

• plus -> teakit-arith/references/plus.md
• toFormat -> teakit-arith/references/to-format.md
• isGreaterThanOrEqualTo -> teakit-arith/references/is-greater-than-or-equal-to.md
