Displaying decimals in JavaScript??

Expand Post »

I am new to JavaScript and have what may be a very simple and easy question to most. I am writing a simple block of code that I need to display dollar amounts with 2 decimals for change. For example instead of displaying the number 5, I need it to display 5.00. How can I do this? Any help will be greatly appreciated.

Re: Displaying decimals in JavaScript??

hello see this code:
it will print 200 as 200.00

javascript Syntax (Toggle Plain Text)
<script language="javascript">
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;
    // alert(s);
    return s;
}
</script>
