I am facing the issue in division of numbers in java script.
Example:
var x= 2500, var y = 100
alert(x/y)
is showing 25.
I need the answer in 25.00 format. What can I do?
When I divide 2536/100, it gives as expected.

You can try number.toFixed(x)
alert( (x/y).toFixed(2) )

You have to use the toPrecision() method: http://www.w3schools.com/jsref/jsref_toprecision.asp It's a method defined in Number's prototype. If you want to dynamically retrieve a float number with a specific precision (in your case 2), you can do de following:
var x = 2500;
var y = 100;
var res = x/y;
var desiredNumberOfDecimals = 2;
var floatRes = res.toPrecision(String(res).length + desiredNumberOfDecimals);

Try doing it this way:
alert((x/y).toFixed(2))
Comments
var x = 2500;
var y = 100;
alert( (x/y).toFixed(2) );

is it possible to enter x and y as a dollar amount? ie 25.00 and 1.00? if so then use the parseFloat method.
var x = 25.00
var y = 1.00
alert(parseFloat(x/y));

Welcome to the Stackoverflow. Your answer is not answering the question; Instead, you have changed the question indeed. So, in that case, it's better to tell your opinion/hint as a comment (which you cannot comment right now, cause of your current score). So, Please try to give a related answer, without changing the question conditions (
var x= 2500, var y = 100)You need to take a look at number formatting and decimal precision etc. Look here: http://www.mredkj.com/javascript/nfbasic2.html
