JavaScript Math Object

$JavaScript Math Object$

JavaScript Math Object

JavaScript Contains a Large Set of the Math Objects. Math Objects is used

To Performs the mathematical Operations. List of the All The Math Objects

is given under the Following Table.

Methods of the Math Objects

For the Following List , Suppose

Var number=6.8;

Sr.	Method	Function	How We Use Math Methods
1.	ceil	Return the Upper integer value of the decimal number	var num_ceil=Math.ceil(number); document.write(num_ceil);
2.	floor	Return the Lower integer value of the decimal number	var num_floor=Math.floor(number); document.write(num_floor);
3.	max	Return the Maximum Value Among the set of value	var num_max=Math.max(23,56,78,12); document.write(num_max);
4.	min	Return the Maximum Value Among the set of value	var num_min=Math.min(23,56,78,12); document.write(num_min);
5.	random	Return The random decimal value between 0-1	var num_ran=Math.random(); document.write(num_ran);
6.	round	Return the round up value of the number	var num_rou=Math.round(number); document.write(num_rou);
7.	sqrt	Return the Square Root Value of the Number	var num_sqr=Math.sqrt(number); document.write(num_sqr);
