missing blank lines around headings and fenced code blocks (e.g., "## Build
Commands", "### Solidity (Foundry)", the triple-backtick code blocks under
Rust/JavaScript/WASM/Nix, and other "###" section headers); fix by adding a
single blank line before and after each heading and ensuring there is a blank
line above and below every fenced code block (the ```bash blocks) so that
headings like "## Build Commands", "### Solidity (Foundry)", "### Rust", "###
JavaScript/WASM", "### Nix" and their adjacent code fences conform to
markdownlint rules MD022/MD031.

[etherscan] table entry base_sepolia to the hyphenated quoted key "base-sepolia"
so vm.rpcUrl(...) and etherscan lookups resolve correctly, ensuring you update
both the RPC variable line (base_sepolia = ...) and the etherscan mapping
arbitrum/base/base_sepolia = ... to use "base-sepolia" instead of base_sepolia.

| # CLAUDE.md | ||
|
|
||
| This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository. | ||
|
|
||
| ## Project Overview | ||
|
|
||
| Decimal floating-point math library for Rainlang/DeFi. The `Float` type packs a 224-bit signed coefficient and 32-bit signed exponent into a single `bytes32`. Decimal (not binary) representation ensures exact decimal values (e.g., `0.1`). No NaN, Infinity, or negative zero — operations error on nonsense rather than producing special values. | ||
|
|
||
| Dual implementation: Solidity for on-chain, Rust/WASM for off-chain JS/TS consumption. The Rust crate uses revm to execute Solidity via an in-memory EVM, ensuring identical behavior. | ||
|
|
||
| ## Build Commands | ||
|
|
||
| ### Solidity (Foundry) | ||
| ```bash | ||
| forge build # Compile contracts | ||
| forge test # Run all Solidity tests (5096 fuzz runs) | ||
| forge test --mt testFunctionName # Run specific test by name | ||
| forge test -vvvv # Verbose trace output for debugging | ||
| ``` | ||
|
|
||
| ### Rust | ||
| ```bash | ||
| cargo build # Build native | ||
| cargo build --target wasm32-unknown-unknown --lib -r # Build WASM | ||
| cargo test # Run Rust tests | ||
| cargo test test_name # Run specific test | ||
| ``` | ||
|
|
||
| Rust tests depend on Foundry build artifacts (`out/`). Run `forge build` before `cargo test` if artifacts are missing. | ||
|
|
||
| ### JavaScript/WASM | ||
| ```bash | ||
| npm install | ||
| npm run build # Full pipeline: Rust WASM → wasm-bindgen → base64 embed → CJS/ESM dist | ||
| npm test # TypeScript type check + vitest (tests in test_js/) | ||
| ``` | ||
|
|
||
| ### Nix | ||
| ```bash | ||
| nix develop # Enter dev shell with all tooling | ||
| ``` | ||
|
|
||
| ## Architecture | ||
|
|
||
| ### Solidity Layer (`src/`) | ||
| - **`lib/LibDecimalFloat.sol`** — Public API: arithmetic, comparison, conversion, formatting, parsing. User-defined type `Float` wrapping `bytes32`. | ||
| - **`lib/implementation/`** — Internal arithmetic (512-bit intermediates for mul/div), normalization, packing. | ||
| - **`lib/parse/`** — String-to-Float parsing. | ||
| - **`lib/format/`** — Float-to-string formatting. | ||
| - **`lib/table/`** — Log lookup tables (deployed as a data contract at a deterministic address). | ||
| - **`concrete/DecimalFloat.sol`** — Exposes library functions as contract methods (required for Rust/revm interop via ABI). | ||
| - **`error/`** — Custom error definitions (CoefficientOverflow, ExponentOverflow, DivisionByZero, etc.). | ||
|
|
||
| ### Rust Layer (`crates/float/`) | ||
| - **`lib.rs`** — `Float` struct wrapping `B256`, implements `Add`/`Sub`/`Mul`/`Div`/`Neg`. Uses `alloy::sol!` macro to generate bindings from Foundry JSON artifacts in `out/`. | ||
| - **`js_api.rs`** — `#[wasm_bindgen]` exports for JS consumption (parse, format, arithmetic, conversions). | ||
| - **`evm.rs`** — In-memory EVM setup via revm. All Rust float operations delegate to Solidity through this. | ||
| - **`error.rs`** — Maps Solidity error selectors to Rust error types. | ||
|
|
||
| ### JavaScript Layer | ||
| - **`scripts/build.js`** — Build pipeline: compiles WASM, runs wasm-bindgen, base64-encodes WASM into JS modules for both CJS and ESM. | ||
| - **`test_js/`** — Vitest tests for the WASM bindings. | ||
| - **`dist/`** — Generated output (CJS + ESM with embedded WASM). | ||
|
|
||
| ### Dependencies (`lib/`) | ||
| Git submodules: forge-std, rain.string, rain.datacontract, rain.math.fixedpoint, rain.deploy, rain.sol.codegen. | ||
|
|
||
| ## Key Design Details | ||
|
|
||
| - 512-bit intermediate values in multiply/divide to preserve precision. | ||
| - Exponent underflow silently rounds toward zero; exponent overflow reverts. | ||
| - Log/power use lookup table approximations with linear interpolation (table deployed as a data contract). | ||
| - Two packing modes: lossless (reverts on precision loss) and lossy (returns bool flag). | ||
| - Solidity compiler: 0.8.25, EVM target: Cancun, optimizer: 1,000,000 runs. | ||

🧹 Nitpick | 🔵 Trivial
Split this agent guide into a docs-only follow-up.
This file is orthogonal to the Base Sepolia / deploy-path change, so keeping it in the same PR makes the deployment review harder to reason about.
Based on learnings, in the rainlanguage/rain.math.float repository, the maintainer 0xgleb prefers to handle documentation additions and improvements in separate issues rather than inline with feature PRs.

Fix the markdownlint spacing violations.
MD022 and MD031 are already firing across the new headings and fenced blocks, so this file will keep the docs lint noisy until blank lines are added around those sections.

Foundry Alloy chain aliases base-sepolia documentation
💡 Result:
In Foundry, the chain keys you use in TOML config files (e.g., deployments.toml) must be either a numeric chain id ([84532]) or a valid Alloy chain alias (like [base-sepolia]). If you use a custom name that isn’t an Alloy alias, you’ll hit InvalidChainKey. [1]
Where it’s documented / defined
- Foundry docs (chain keys + Alloy aliases +
InvalidChainKey): “Scripting with config” guide. [1] - Alloy alias exists:
alloy_chains::Chain::base_sepolia()(shows Base Sepolia is a known chain in Alloy’s chain list). [2]
Base Sepolia network details (for your endpoint_url)
- Chain ID: 84532; RPC: https://sepolia.base.org. [3][4]
Example
# deployments.toml
[base-sepolia]
endpoint_url = "https://sepolia.base.org"(Or use [84532] instead of [base-sepolia] for maximum compatibility.) [1][3]
Use the canonical Base Sepolia alias spelling in foundry.toml.
The base_sepolia keys will not be resolved by vm.rpcUrl(...) or etherscan lookups. Foundry's documented Alloy chain alias for Base Sepolia is base-sepolia (with hyphens), not underscores. TOML keys with hyphens must be quoted.
