JavaScript Number toString() Method (original) (raw)

Last Updated : 09 Jan, 2025

The toString() method in JavaScript returns a number as a string. It allows converting numerical values to string representations, enabling operations like formatting output, displaying numbers in various formats, and facilitating string manipulation based on numeric values.

**Syntax:

num.toString(base)

**Parameters: This method accepts a single optional parameter

**base: It is an integer between 2 and 36 which is used to specify the base for representing numeric values.

**Return Value: The **num.toString() method returns a string representing the specified number object.

**Below is an example of the Number toString() Method:

**Example 1: Converting a number to a string with base 2, we will have to call the toString() method by passing 2 as a parameter.

JavaScript `

let num=213; console.log("Output : " + num.toString(2));

**Output:

Output:11010101

**Example 2: Converting a number to a string with base 8, we will have to call the toString() method by passing 8 as a parameter.

JavaScript `

let num=213; console.log("Output : " + num.toString(8));

**Output:

Output : 325

**Example 3: Converting a number to a string with base 16, we will have to call the toString() method by passing 16 as a parameter.

JavaScript `

let num=213; console.log("Output : " + num.toString(16));

**Output:

Output : d5

**Example 4: If the toString() method is called without passing any parameter then the number will be converted to a string without change in BASE. Below is the program to illustrate this.

JavaScript `

let num=213; console.log("Output : " + num.toString());

**Output:

Output :213
