**Math And Rounding In JavaScript**: Hello everyone, welcome to the nkcoderz.com website. In this article we will going to discuss about the Math And Rounding In JavaScript.

## Math And Rounding In JavaScript

JavaScript provides several built-in methods for performing mathematical operations and rounding numbers.

Here are some of the most commonly used mathematical operations in JavaScript:

- Addition:
`+`

- Subtraction:
`-`

- Multiplication:
`*`

- Division:
`/`

- Remainder (modulo):
`%`

To round numbers in JavaScript, you can use the `Math.round()`

method, which rounds a number to the nearest integer:

## Code For Math.round() Method In JS

```
let num = 4.6;
let result = Math.round(num);
console.log(result);
```

## Output

5

You can also use the `Math.floor()`

method to round a number down to the nearest integer:

## Code For Math.floor() Method In JS

```
let num = 4.6;
let result = Math.floor(num);
console.log(result);
```

## Output

4

And the `Math.ceil()`

method to round a number up to the nearest integer:

## Code For Math.ceil() Method In JS

```
let num = 4.1;
let result = Math.ceil(num);
console.log(result);
```

## Output

5

For more specific rounding, you can use the `.toFixed()`

method on a number. This method returns a string representation of the number rounded to a specified number of decimal places:

## Code For toFixed() Method In JS

```
let num = 4.666666;
let result = num.toFixed(2);
console.log(result);
```

## Output

“4.67”
