# How to Get Decimal Part of Number in Javascript

In this tutorial, you will learn how to get decimal part of number in javascript. The number whose whole number part and the fractional part are separated by a decimal point is known as a decimal number. The fractional part is also known as the decimal part. For example, 6.58 is a decimal number where 6 is the whole number and 58 is the decimal part.

To get the decimal part of the decimal number, we can make use of the `split()` method. This method is only available for strings, so if the value is of number type, then we have to convert it into string type using the `toString()` method and then convert it back to number type using the `Number()` method.

In the following example, we have an input field in which we will enter a random decimal number. Upon click of a button, we will get the decimal part and display that on the screen.  Please have a look over the code example and the steps given below.

HTML & CSS

• We have 4 elements in the HTML file (`div`, `input`, `button`, and `h1`). The `div` element is just a wrapper for the rest of the elements.
• The `innerText` for the `button` element is `“Get”` and for the `h1` element, it is `“Result”`.
• We have done some basic styling using CSS and added the link to our `style.css` stylesheet inside the `head` element.
• We have also included our javascript file `script.js` with a `script` tag at the bottom.

<button>Get</button>
<h1>Result</h1>
</div>

<script src="script.js"></script>
</body>

</html>```
```.container {
text-align: center;
}

button {
margin-top: 10px;
}

input {
display: block;
margin: 10px auto;
}

input[type=number]::-webkit-inner-spin-button,
input[type=number]::-webkit-outer-spin-button {
-webkit-appearance: none;
margin: 0;
}```

Javascript

• We have selected the `input` element, `button` element, and `h1` element using the `document.querySelector()` method and stored them in `input`, `btnGet`, and `output` variables respectively.
• We have attached a `click` event listener to the `button` element.
• In the event handler function, we are getting the value from the `input` element using `value` property and storing that in the `num` variable.
• We are calling the `split()` method to split `num` into two parts and storing the second part in the `result` variable.
• We are converting `num` back to number type using `Number()` method.
• We are displaying the `result` in the `h1` element using the `innerText` property.
```let input = document.querySelector("input");
let btnGet = document.querySelector("button");
let output = document.querySelector("h1");
