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 0 — Jacob George, Jul 27 '12 at 09:48

Use .toFixed:

var num = 45;
num.toFixed(2); //"45.00"

It should be mentioned that the return value will be a `string` and not a `float` – Fr0zenFyr Jun 13 '17 at 12:39

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)        // 10.22

Explanation 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.
