In this article, we will show you how to round a number to 2 decimal places in JavaScript.

Use the `toFixed()` method to round a number to decimal place in JavaScript. The toFixed() method is used to return a string representation of a number of digits after the decimal point.

The toFixed() method is used to format a number using fixed-point notation. It can be used to format a number with a specific number of digits to the right of the decimal.

### Example 1:

``````const number = 28.319921
const rounded_number = number.toFixed(2)
// Output: 28.32``````

Here, `.toFixed(2)` method convert the 28.319921 number into number with only 2 decimal points.

### Example 2:

``````const number = 28
const rounded_number = number.toFixed(3)
// Output: 28.000``````

The `.toFixed(3)` method keeping three decimals even though they’re zero.

### Example 3:

Now, we will convert the number with decimal points to a rounded whole number. If we give a value of `0` to the `.toFixed()` method, it will round the whole number. Also If there is no parameter passed in the toFixed() method then it doesn’t display any digits after the decimal place.

``````const number = 28.319921
const rounded_number = number.toFixed(0)
// Output: 28``````

That’s it for today.
