# How to Get Only 2 Digits After Decimal in Javascript

In this tutorial, you will learn how to get only 2 digits after decimal in javascript. When we carry out a specific calculation and generate a decimal value, there is a good probability that many digits will come after the decimal point. For ease of understanding, numbers are rounded to a predetermined number of decimal places. For a newbie developer, it can be a bit tricky to get only 2 digits after decimal.

There are numerous ways to get only 2 digits after decimal. We are going to use the simplest approach which involves the usage of the `toFixed()` method. It converts the number to string and rounds it to a specified number of decimals.

In the following example, we have one global variable that holds a number. Upon click of a button, we will get only 2 digits after decimal in the number and display the result on the screen. Please have a look over the code example and the steps given below.

• We have selected 2 elements (`button` and `h1`) using the `document.querySelector()` method and stored them in `btn` and `result` variables.
• We have created a global variable `num` that holds a decimal number as a value.
• We have added a `click` event listener to the `button` element.
• We are executing the `toFixed()` method and passing 2 as a parameter. As a result, it will round the number to 2 decimal places.
• We will display the result in the `h1` element.
```let btnGet = document.querySelector('button');
let result = document.querySelector('h1');

let num = 201.543216879762;
