Formats

Formats now exist in their own files and act more or less as plugins. Check out the bytes format for an example of how to create one.

Locales

When naming locale files use the ISO 639-1 language codes supplemented by ISO 3166-1 country codes when necessary.

Locale translations will not be merged without unit tests.

See the english unit tests for an example.

2.0.0

2.0.0 brings a lot of breaking changes and a reorganization of the repo, but also simplifies the api as well as the creating of custom formats.

Breaking change / Feature: All formats are now separate files. This makes it easy to create custom formats, and will also allow for custom builds with only certain formats. (Note: The built numeral.js still contains all formats in the repo).

Breaking change / Feature: All formats and locales are now loaded using numeral.register(type, name, {})

Breaking change: All language now renamed to locale and standardized to all lowercase filenames

Breaking change: The locale function no longer loads locales, it only sets the current locale

Breaking change: The unformat function has been removed numeral().unformat(string) and now happens on numeral init numeral(string)

Breaking change / Feature: Bytes are now formatted as: b (base 1000) and ib (base 1024)

Breaking change: numeral(NaN) is now treated the same as numeral(null) and no longer throws an error

Feature: Exponential format using e+ or e-

Bug fix: Update to floating point helpers (Note: Numeral does not fix JS floating point errors, but look to our tests to see that it covers quite a few cases.)
