3. Run `npm install` to install dependencies

4. Create a new branch from `develop`

5. Add your tests to the files in `/tests`

6. To test your tests, run `grunt`

7. When all your tests are passing, run `grunt dist` to compile and minify all files

8. Submit a pull request to the `develop` branch.


### Formats

Formats now exist in their own files and act more or less as plugins. Check out the [bytes format](https://github.com/adamwdraper/Numeral-js/blob/master/src/formats/bytes.js) for an example of how to create one.


### Locales

When naming locale files use the [ISO 639-1 language codes](http://en.wikipedia.org/wiki/List_of_ISO_639-1_codes) supplemented by [ISO 3166-1](http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2) country codes when necessary.

### Locale translations will not be merged without unit tests.

See [the english unit tests](https://github.com/adamwdraper/Numeral-js/blob/master/tests/locales/en-gb.js) for an example.


# Changelog

### 2.0.6

Bug fix: Multi letter currency symbols and spacing

Added: Formatting of numbers with leading zeros

New format: Basic Point

### 2.0.2

Bug fix: Updated module definitions

### 2.0.1

Bug fix: Fixed regression for webpack/browserify/rollup

### 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.)

### 1.5.6

Bug fix: numeral converts strings to numbers

Bug fix: Null values return same as 0

### 1.5.5

Bug fix: Switch bytes back to `b` and change iecBinary to `ib`, and calculate both using 1024 for backwards compatibility

### 1.5.4
