# Round a Number to 2 Decimal Places in JavaScript

To round a number to decimal places in Javascript, use either the .toFixed() or Math.round() function. In this tutorial we will learn how to use both methods.

## Rounding a Number to 2 Decimal Places with .toFixed()

The .toFixed() function will round a number to a fixed number of decimal places. Pass the number to round before the function and the number of decimal places to round to as the first argument.

```
var num = 22.22434;
var num2 = 1.004
var res = num.toFixed(2);
console.log(res);
```

```
22.22
```

**Note** – This method will not work on numbers like 1.004.

## Rounding a Number in JavaScript to 2 Decimal Places with Math.round()

To round numbers to 2 decimal places with improved accuracy, use the Math.round() function with the Number.EPSILON utility like this:

```
var num = 22.22434;
var res = Math.round((num + Number.EPSILON) * 100) / 100;
console.log(res);
```

```
22.22
```

**Note** – This method will not work on numbers like 1.004.

## Round Numbers with Multiple 0's Decimal Places

The two previous methods will not round numbers like 1.005 to two decimal places accurately. To get around this, we will use the `.toPrecision()`

function to remove rounding errors before getting the final result.

```
function round(num) {
var m = Number((Math.abs(num) * 100).toPrecision(15));
return Math.round(m) / 100 * Math.sign(num);
}
console.log(round(1.005));
```
