# How to Truncate Number to Two Decimal Places without Rounding in Javascript

In this tutorial, you will learn how to truncate number to two decimal places without rounding in javascript. Sometimes the complete number rather than just the decimal point is what matters, even when a number’s decimal representation gives an exact value. From a developer perspective, it can be a bit tricky to truncate a number to two decimal places without rounding.

There are numerous ways to truncate a number to two decimal places without rounding. We are going to use the simplest approach which involves the usage of the `Math` object. This object contains `trunc()` method which removes the decimal part and returns the integer part of a number.

In the following example, we have one global variable that holds a decimal number. Upon click of a button, we will truncate the number to two decimal places without rounding and display the result on the screen.  Please have a look over the code example and the steps given below.

HTML & CSS

• We have 3 elements in the HTML file (`div``button`, and `h1`). The `div` element is just a wrapper for the rest of the elements.
• The `innerText` for the `button` element is `“Remove”`.
• 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.
```<!DOCTYPE html>
<html lang="en">

<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<link rel="stylesheet" href="style.css">
<title>Document</title>
</head>

<body>

<div class="container">
<button>Remove</button>
<h1>Result</h1>
</div>

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

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

button {
margin-top: 10px;
padding: 10px 20px;
}
```

Javascript

• We have selected the `button` element and `h1` element using the `document.querySelector()` method and stored them in `btnRemove` and `output` variables respectively.
• We have attached a `click` event listener to the `button` element.
• We have a global variable `myNum` which holds a decimal number as its value.
• We are displaying the original number in the `h1` element using the `innerText` property.
• In the event handler function, we are calling `trunc()` method of Math object and passing `myNum` as a parameter. As a result, it will remove decimal places without rounding and will return the integer part.
• The returned value is stored in the `result` variable.
• We are displaying the `result` in the `h1` element using the `innerText` property.
```let btnRemove = document.querySelector("button");
let output = document.querySelector("h1");

let myNum= 521336.47445521;

output.innerText = myNum;

btnRemove.addEventListener("click", () => {
let result = Math.trunc(myNum);
output.innerText = result;
});```
