In addition to relaxatraja's suggestion to use toFixed(), here is a full currency formatter with American number conventions:

var number:Number = 13458900.3;
var formatted:String = number.toFixed(2);
formatted = "$" + formatted.replace(formatted.indexOf(".") > -1 ? /(?<=\d)(?=(\d\d\d)+(?!\d)(?:\.\d*))/g : /(?<=\d)(?=(\d\d\d)+(?!\d))/g, ",").replace(/,{2,}/g, ",");
trace(formatted);

If you dont want the conversion then just use

txtDisplay.text="$"+floatValue;

If you want true currency format then you need to deal with String operations to analyze the value that is being displayed and adjust it with "$", "0", and "," characters as needed.

For instance, you can analyze the string to see if it has a ddecimal point, and if not, you know you need to tack on ".00", and if it does have a decimal you check to see what the index of that decimal is relative to the last character to determine if you need to add a "0". Then you can split off the leading part and place commas in where they belong. And then, as a final step you sew the parts back together and tack on a "$"

You might be able to find something searching Google that will show you how to manage it if you use search terms like "AS3 currency format"

While I don't have it myself, I have read that CS5 has a CurrencyFormat class, so maybe it's time to sway your boss into upgrading your tools.
