		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.

### Available options
