# How to Remove Trailing Zeros After Decimal in Javascript

In this tutorial, you will learn how to remove trailing zeros after decimal in javascript. In a decimal number, the whole number part and the fractional part are separated by a decimal point. For example, 3.3500 is a decimal number where 3 is the whole number and 3500 is the decimal part. As you can see, it also contains unnecessary trailing zeros.

To get rid of unnecessary trailing zeros in the decimal number, we can make use of the `Number()` method. It works with string as well as number types.

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 remove the trailing zeros and display the decimal number 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.

<div class="container">
<input type="number" placeholder="Enter Number">
<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. Since it is coming from an `input` element, it is by default of string type.
• We are calling the `Number()` method to convert `num` into number type and storing that in the `result` variable.
• 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");
