## README

# `intl-numberformat`

We've migrated the docs to https://formatjs.github.io/docs/polyfills/intl-numberformat.

Digit grouping preserves complete Unicode digits, including supplementary-plane
numbering systems, and follows the locale's primary and secondary group sizes.

Numeric digit mappings follow pinned CLDR data, including Lepcha and newer
Unicode numbering systems. Which systems a locale accepts depends on its loaded
locale data.
