The new portuguese function is imported but not re-exported alongside the other language helpers, so import { portuguese } from 'numberstring' will fail even though the README and API imply it exists. This is a user-facing API regression specific to the new language: only toWords(..., { lang: 'pt' }) works, but the named export does not.

Portuguese uses “e” between a higher-scale group and the thousands group (e.g., 1,001,000 → “um milhão e mil”). The join logic explicitly skips inserting “e” when the current part contains mil, which yields outputs like “um milhão mil” for any number where the thousands group is non-zero and a higher group exists. This produces incorrect wording for common inputs such as 1,001,000 or 2,005,000.

CI runs tests from the root, so server test dependencies need to be in the main package.json. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Add portuguese to named exports in index.js (Codex review) - Fix Portuguese join logic to correctly use "e" between higher scale groups (milhão/bilhão) and thousands (mil) - Add comprehensive Portuguese test suite with 8 test cases - Add toWords test for Portuguese language Fixes the issue where "um milhão mil" was output instead of the correct "um milhão e mil" for 1,001,000.

- Add PR review workflow section with guidance on checking comments - Add supported languages list (9 languages now supported) - Add features section documenting full capabilities - Emphasize running lint/tests before commits as first step Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
