Since the built-in JavaScript/jQuery `sort()` function treats everything as strings, you may have trouble dealing with floating-point values in a JS array:

```let arrayNum = [-99, 1.10, 20.50, 3.60, 5.10, 0, 100];
arrayNum.sort();
=> -99, 0, 1.1, 100, 20.5, 3.6, 5.1
```

The jQuery num-sort plugin provides a custom sort function that allows you to sort an array of numbers correctly in descending or ascending order. Happy coding.

## How to use it:

1. Insert the `jquery-num-sort.js` library after loading the latest jQuery.

```<script src="/path/to/cdn/jquery.slim.min.js"></script>
<script src="/path/to/js/include/jquery-num-sort.js"></script>
```

2. Sort an array of numbers in descending order.

```let arrayNum = [-99, 1.10, 20.50, 3.60, 5.10, 0, 100];
let outputDsc = \$(arrayNum).sortDescending();
=> 100,20.5,5.1,3.6,1.1,0,-99
```

3. Sort an array of numbers in ascending order.

```let arrayNum = [-99, 1.10, 20.50, 3.60, 5.10, 0, 100];
let outputAsc = \$(arrayNum).sortAscending();
=> -99,0,1.1,3.6,5.1,20.5,100
```
