RE: Formatting Numbers using JavaScript

can't say much for simpler, but here is a shorter version that i wrote that 
includes commas as well as rounds to the nearest cent:

function format(num){
  if(isNaN(num))
    num = 0;
  var dol = Math.floor(num).toString();
  var cents = Math.floor((num*100+.5)%100).toString();
  for (var i = 0; i < Math.floor((dol.length-1)/3)-i; i++)
    dol = dol.slice(0,-(4*i+3))+','+dol.slice(-(4*i+3));
  while (cents.length<2)
    cents += "0";
  return "$"+dol+"."+cents;
}
