JavaScript Number toString() method

The toString method in JavaScript transforms a specified number into its string representation and subsequently returns that string.

Syntax

The syntax for the toString method is illustrated as follows:

Number.toString(radix)

Parameter

radix - This parameter is optional. It is an integer ranging from 2 to 36 that signifies the numeral system that will be utilized.

Return

The given number in the form of string.

JavaScript Number toString method example

In this section, we will explore the toString method using several illustrative examples.

Example 1

Let's see a simple example of toString method.

<script>

var a=50;

var b=-50;

var c=50.25;

document.writeln(a.toString()+"<br>");

document.writeln(b.toString()+"<br>");

document.writeln(c.toString());

</script>

Output:

50

-50

50.25

Example 2

Let’s examine an illustration that demonstrates how to sum two numbers both with and without the application of the toString method.

<script>

var a=50;

var b=30;

var c=a+b;

document.writeln("Before invoking toString(): "+c+"<br>");

var c=a.toString()+b.toString();

document.writeln("After invoking toString(): "+c);

</script>

Output:

Before invoking toString(): 80

After invoking toString(): 5030

Example 3

In this illustration, we will provide a radix parameter to the toString function.

<script>

var a=12;

document.writeln(a.toString(2)+"<br>");

document.writeln(a.toString(8)+"<br>");

document.writeln(a.toString(16));

</script>

Output:

1100

14
