# Math And Rounding In JavaScript

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);
``````
