Number valueOf( ) Method In JavaScript

The valueof() method in JavaScript is used to return the primitive value of a number.
This method is usually called internally by JavaScript and not explicitly in web code.

Syntax:

number.valueOf()

Return Value:
The valueof() method in JavaScript returns a number representing the primitive value of the specified Number object.

What is Primitive Value?
Primitive values are the type of values that a variable can hold. Primitive value is stored directly in the location that the variable accesses. Primitive values are data that are stored on the stack.
Primitive types include Undefined, Null, Boolean, Number, or String.

Examples:

Input :  213
Output : 213
     
Input : -213
Output :-213

Input :  0
Output : 0

Input :  0/0
Output : NaN

Passing a positive number as an argument in the valueOf() method.

<script type="text/javascript">

var num=213;

document.write("Output : " + num.valueOf());

</script>
OUTPUT:
```
Output : 213
```
Passing a negative number as an argument in the valueOf() method.

<script type="text/javascript">

var num=-213;

document.write("Output : " + num.valueOf());

</script>
OUTPUT:
```
Output : -213
```
Passing a zero as an argument in the valueOf() method.

<script type="text/javascript">

var num=0;

document.write("Output : " + num.valueOf());

</script>
OUTPUT:
```
Output : 0
```
Passing an equation(equating to infinite value) as an argument in the valueOf() method.

<script type="text/javascript">

var num=0/0;

document.write("Output : " + num.valueOf());

</script>
OUTPUT:
```
Output : Nan
```
