The math object in JavaScript bestow various methods and constants to execute mathematical operation. This object doesn’t have any constructors as of date object.

Math Methods in JavaScript

Following is the list of math methods in JavaScript along with a brief description:

Examples and Syntax of the above mentioned methods:

Math.sqrt (n) in JavaScript

The Math.sqrt (n) in JavaScript in returns the square root of the provided number. Here is an example that best describes the square root method in JavaScript.

Example

Square Root of 15 is: <span id="p1"></span>    
<script>    
document.getElementById('p1').innerHTML=Math.sqrt(15);    
</script>    

Math.random () in JavaScript

The Math.random () method in JavaScript returns a random number between 0-1. Here is an example to understand it from a simple point of view.

Example

Random Number is: <span id="p2"></span>    
<script>     
document.getElementById('p2').innerHTML=Math.random();    
</script>   

Math.pow (m,n) in JavaScript

The Math.pow (m,n) method in JavaScript returns the m to the power of n i.e. mn`, basically it returns the value of the sum of the power applied to a number. Here is an example that will best describe this method:

Example

2 to the power of 3 is: <span id="p3"></span>    
<script>    
document.getElementById('p3').innerHTML=Math.pow(2,3);    
</script>   

Math.floor (n) in JavaScript

The Math.floor (n) method in JavaScript returns the lowest integer for a provided number like 2 for 2.7, 4 for 4.6 and so on. Here is an example for this method to let you understand:

Example

Floor of 8.6 is: <span id="p4"></span>   
<script>      
document.getElementById('p4').innerHTML=Math.floor(8.6);    
</script>  

Math.ceil (n) in JavaScript

The Math.ceil (n) method in JavaScript returns the largest integer for a provided value like 2 for 1.4, 3 for 2.5 and so on. Let's understand this with an example:

Example

Ceil of 2.6 is: <span id="p5"></span>    
<script>    
document.getElementById('p5').innerHTML=Math.ceil(2.6);    
</script> 

Math.round (n) in JavaScript

The Math.round (n) method in JavaScript returns the round-off of an integer that is nearest to the provided number. Just like simple math, if the fractional part is less than 0.5, it goes to the lower value 0 otherwise to upper value 1 like, 2 for 1.7, 4 for 4.4 and so on.

Example

Round of 2.3 is: <span id="p6"></span><br>    
Round of 2.7 is: <span id="p7"></span>   
<script>    
document.getElementById('p6').innerHTML=Math.round(2.3);   
document.getElementById('p7').innerHTML=Math.round(2.7);    
</script>    

Math.abs (n) in JavaScript

The Math.abs (n) method in JavaScript returns the utter (absolute) value of the provided number like 2 for -2, 5.5 for -5.5 and so on.

Example

Absolute value of -6 is: <span id="p8"></span>       
<script>     
document.getElementById('p8').innerHTML=Math.abs(-6);      
</script>
