JavaScript Number toString() Method

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.

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. 

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. 

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.

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

Output:

Output :213
