--- name: dimension-core description: > @eristack/dimension normalizeDimension, dimensionVolume, formatDimension — L×W×H decimal strings (Wave 13 B1). Optional unit label; pair with uom in the app. metadata: author: eristack version: "0.0" sources: - packages/primitive/dimension/docs/getting-started.md --- # @eristack/dimension ```ts import { normalizeDimension, dimensionVolume } from "@eristack/dimension"; const d = normalizeDimension({ length: "2", width: "3", height: "4" }); dimensionVolume(d); // "24.000000" ``` ## Checklist 1. `normalizeDimension` on every write — positive finite decimal strings only. 2. Store **canonical** fixed strings from normalize (no JS number literals for sides). 3. `unit` is display/metadata — validate against `@eristack/uom` in the app if needed. 4. Volume scale defaults to 6 dp — pass `{ scale }` for display rounding. ## Do not - Import `@eristack/uom` from this package core - Use `Number()` on length/width/height at the API boundary
