display amount with 2 decimal (eg:12.30)

http://www.irt.org/script/7.htm         Q7 How do you round a number to a X decimal places?
<script language="JavaScript"><!--
function round(number,X) {
// rounds number to X decimal places, defaults to 2
    X = (!X ? 2 : X);
    return Math.round(number*Math.pow(10,X))/Math.pow(10,X);
}

document.write(round(1,2)+'<BR>');
document.write(round(1.2,2)+'<BR>');
document.write(round(1.23,2)+'<BR>');
document.write(round(1.234,2)+'<BR>');
document.write(round(1.2345)+'<BR>');

"This article will show you how to do two things:  Round numbers to the nearest hundredth, with two digits following the decimal point....Insert commas between every third digit (right to left) for numbers 1000 and larger.... "

function CurrencyFormatted(amount)
{
      var i = parseFloat(amount);
      if(isNaN(i)) { i = 0.00; }
      var minus = '';
      if(i < 0) { minus = '-'; }
      i = Math.abs(i);
      i = parseInt((i + .005) * 100);
      i = i / 100;
      s = new String(i);
      if(s.indexOf('.') < 0) { s += '.00'; }
      if(s.indexOf('.') == (s.length - 2)) { s += '0'; }
      s = minus + s;
      return s;
}
// end of function CurrencyFormatted()

tks for quick respond ;-)
let me try it out later.

ok, its working, but i would like to point out that to insert comma, this script has to be used:

function CommaFormatted(amount)
{
      var delimiter = ","; // replace comma if desired
      var a = amount.split('.',2)
      var d = a[1];
      var i = parseInt(a[0]);
      if(isNaN(i)) { return ''; }
      var minus = '';
      if(i < 0) { minus = '-'; }
      i = Math.abs(i);
      var n = new String(i);
      var a = [];
      while(n.length > 3)
      {
            var nn = n.substr(n.length-3);
            a.unshift(nn);
            n = n.substr(0,n.length-3);
      }
      if(n.length > 0) { a.unshift(n); }
      n = a.join(delimiter);
      if(d.length < 1) { amount = n; }
      else { amount = n + '.' + d; }
      amount = minus + amount;
      return amount;
}

var result = CurrencyFormatted(number);
result = CommaFormatted(result);

(Select, copy, paste that into notepad, save as c:\temp\currency.htm then type c:\temp\currency.htm in address bar in your browser)

oh, sorry, didnt see ur post ;-)
i'm going to accept ur answer with A anyway..

my tks to you again, callrs ;-)
have a nice day

I beat you to it by just under a minute :)

Try the demo, it's cool
