I am trying to calculate a total of dynamically created text boxes. I am getting the wrong values when I use the “parseFloat” function.

The Code:
~~~~~~~~~

var f = document.forms.item("frmCalculate")
  var total = 0;
   
  for (var i = 0; i < f.length; i++)
  {
    var e = f.elements(i)
    if (e.name == "Per_Value")
    {
      total += parseFloat(e.value)
      alert(total)  //Testing
    }
  }
  alert(total)  //Testing

The Values:
~~~~~~~~~~~
   1.  62.84
   2.  32.43
   3.  4.73

The result:
~~~~~~~~~~~
   100.00000000000001

I know the result should be 100, but why is it not??
