JavaScript : Rounding number to decimal formats to display currency

Was looking for ways to round up float numbers to 2 decimal points and also to display currency with Javascript. Below is just a code fragment in JavaScript on how to properly format integer to display currency or money and for rounding up to 2 decimal points.

 var money = 12.3456789;
 var roundedMoney = money.toFixed(2); // round to 2 decimal points

 alert("Before : $" + money)
 alert("After : $" + roundedMoney)
