Hey readers, in this article we will be discussing how to use the toFixed method in JavaScript in a step-wise, efficient manner. If you are a beginner and want to learn JavaScript then do check out the course on Codedamn.

Introduction

JavaScript is one of the most used languages when it comes to building web applications as it allows developers to wrap HTML and CSS code in it to make web apps interactive. It allows a web application to be interactive. It is also used for making animations on websites and has a large community on GitHub. JavaScript has tons of libraries, one of which is React which we will be covering in this article later. 

Use cases: 

  • Building web server and its interactive functions
  • Animations and graphics, adding special effects to web components
  • Validating forms and exception errors
  • Adding behavior and functionalities to web pages

Since JavaScript is a scripting language, it works without any libraries. Developers are free to write JavaScript language code anywhere and can still run it in the browser. There is no structure in JavaScript, the browser executes each line of the code from top to down.

toFixed method

In JavaScript, the toFixed() method is used to format a number in fixed-point notation. It can be used to format a number to the right of the decimal with a certain amount of digits.

Syntax:

number.toFixed( value )

The toFixed() method is used with a number using the ‘.’ operator, as indicated in the above syntax. This method uses fixed-point notation to format a number.

This method only accepts a single parameter value. It denotes how many digits will appear following the decimal point.

It returns a number in string form as the return value. According to the toFixed() method, the number has the precise amount of digits after the decimal place.

Example

Using the method toFixed() without any parameters: If no parameter is given in the toFixed() method, no digits after the decimal place are displayed.

<script type="text/javascript">
var test=213.73145;
document.write(test.toFixed()); 
</script>

Using the toFixed() function with the following parameter: The toFixed() method will return a number written as a string with exactly that amount of digits after the decimal place if a parameter is given.

<script type="text/javascript">
var test=213.73145;
document.write(test.toFixed(3)); 
</script>

Using the toFixed() function to convert an exponential number into a string representation with a certain number of digits after the decimal place: The toFixed() method can be used to convert an exponential number into a string representation with a specific number of digits after the decimal place.

<script type="text/javascript">
var test=2.13e+15;
document.write(test.toFixed(2)); 
</script>

Uses of toFixed() method

A number is converted to a string using the toFixed() function.

The toFixed() method takes a string and rounds it to a specified number of decimals.
