[Javascript] Multiplication

[Steve Blades]

function moneyFormat(input) {
   var dollars = Math.floor(input);
   var tmp = new String(input);

   for ( var decimalAt = 0; decimalAt < tmp.length; decimalAt++ ) {
      if ( tmp.charAt(decimalAt)=="." )
         break;
   }

   var cents  = "" + Math.round(input * 100);
   cents = cents.substring(cents.length-2, cents.length)
           dollars += ((tmp.charAt(decimalAt+2)=="9")&&(cents=="00"))? 1 : 
0;

   if ( cents == "0" )
      cents = "00";

   return(dollars + "." + cents);
}

Hi,
    I've looked in my JavaScript book and I can't find anything like the
VBScript formatNumber function. You may have to define your own. I guess it
would be easy to do. Just check if it is a valid number format and then
check how many (if any) numbers are after the decimal point using indexOf()
and add the zeros accordingly.

Think this has been asked before but how do I format numbers after
multiplication

eg

var myNumber=6*1.5

that returns 9 but how do I make it 9.00

or how do I make 3*1.5     4.50  rather than 4.5

In ASP we would just go formatnumber(myNumber,2)  is there no similar
function in Javascript?

Andrew
