Here is a working example in both Javascript and jQuery:

http://jsfiddle.net/GuLYN/312/

//In jQuery
$("#calculate").click(function() {
    var num = parseFloat($("#textbox").val());
    var new_num = $("#textbox").val(num.toFixed(2));
});


// In javascript
document.getElementById('calculate').onclick = function() {
    var num = parseFloat(document.getElementById('textbox').value);
    var new_num = num.toFixed(2);
    document.getElementById('textbox').value = new_num;
};
?

You could use a variable to make the calculation and use toFixed when you set the  diskamountUnit element value   var amount       disk   slider  value     1 60      diskamountUnit   val       amount toFixed 2      You can also do that in one step  in the val method call but IMO the first way is more readable       diskamountUnit   val            disk   slider  value     1 60  toFixed 2
