## Usage

`format(interval, options)`

```js
var format = require('math-interval-formatter');

var interval = {
	from: {
		value: -Math.PI,
		included: true
	},
	to: {
		value: Infinity,
		included: false
	}
};

format(interval);
//=> '[-3.142,Infinity)'

format(interval, {
	format: 'pretty',
	infiniteEndpoints: 'math',
	numberFormat: '+0.0000'
});
//=> '[3.1416, +∞)'

```

See tests for more details.
