JavaScript: formatting number with exactly two decimals

Getting a bit muddled up using variables and now cant seem to get calculation to work at all!?

 $("#discount").change(function(){
            var list = $("#list").val();
            var discount = $("#discount").val();
            var price = $("#price");
            var temp = discount * list;
            var temp1 = list - temp;
            var total = parseFloat($(this).temp1()).toFixed(2);

            price.val(total);       
 });

$(this).temp1() looks particularly out of place, I think you just meant to use the temp1 variable. Since it’s already a number, you don’t need to use parseFloat on it either:

$("#discount").change(function() {
    var list = $("#list").val();
    var discount = $("#discount").val();
    var price = $("#price");
    var temp = discount * list;
    var temp1 = list - temp;
    var total = temp1.toFixed(2);

    price.val(total);
});
