# Utility Methods

The `panel-utils` module encapsulates multiple utility methods for panel settings, such as screen adaptation, colors, numbers, time, strings, and temperature. You can use these methods to easily develop smart products.

## How to get started

```shell
$ yarn add @ray-js/panel-sdk

# or

$ npm install @ray-js/panel-sdk
```

then

```javascript
import { utils } from '@ray-js/panel-sdk';

utils.toFixed('111', 5); // '00111'
```
