Number to Decimal Mark

Introduction

In this lab, we will explore the Number object in JavaScript and learn how to convert a number to a decimal mark formatted string. We will use the toLocaleString() method to achieve this. By the end of the lab, you will have a solid understanding of how to format numbers in a readable and user-friendly way.

How to Convert a Number to Decimal Mark Format

To convert a number to decimal mark format, follow these steps:

1. Open the Terminal/SSH and type node to start practicing coding.
2. Use Number.prototype.toLocaleString() to convert the number to decimal mark format.
3. The following code can be used for this process:

const toDecimalMark = (num) => num.toLocaleString("en-US");

Here's an example of how to use this function:

toDecimalMark(12305030388.9087); // '12,305,030,388.909'

This will convert the number 12305030388.9087 to the decimal mark formatted string '12,305,030,388.909'.
