you have to explain more, if you want the conversion for display purposes, 11 + ".00" will do. If you convert interger to float, the decimal places are always 0Jacob George– Jacob George2012-07-27 09:48:24 +00:00Commented Jul 27, 2012 at 9:48

var num = 10;
var result = num.toFixed(2);

This a very common problem I see someone has already answered, I want to add to it, if you want to further use the number after conversion for calculations Try this in console
a = 10.2222;
console.log(typeof a) // "number"
console.log(a) // 10.2222
b = parseFloat(a).toFixed(2);
console.log(typeof b) // "String"
console.log(b) // "10.22"
c = parseFloat(b)
console.log(typeof c) // "number"
console.log(c) // 10.22Explanation is-
toFixed() method outputs a string variable
but if you want to further use the value of b as a 'number'
you will have to,
c = parseFloat(b)
typeof c
// "number"

Just add toFixed(2) here with your variable.
