## Example

```js
{ type: Types.NumberArray }
```

## Options

`separator` `string` - is used to join values when calling the `.format()` function. Defaults to `' | '`

`format` `string` - string to be used as the default formatString in the `.format()` method (below). This defaults to `0,0[.][000000000000]`.

## Underscore methods

`format(formatString, separator)` - concatenates and formats the stored values to `string` using [numeraljs](http://numeraljs.com/), according to the format string provided.

Defaults to `0,0[.][000000000000]` and can be set to `false` to disable automatic formatting.

`separator` defaults to the value of `separator` option.

## Methods
