JavaScript Number toString() method in Javascript is used with a number and converts the number to a string. It is used to return a string representing the specified Number object.

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: 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: 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
