I have a form for my customers to add budget projections. A prominent user wants to be able to show dollar values in either dollars, Kila-dollars or Mega-dollars.

I'm trying to achieve this with a group of radio buttons that call the following JavaScript function, but am having problems with rounding that make the results look pretty crummy.

Any advice would be much appreciated!

function setDollars(new_mode)
 {
  var factor;
  var myfield;
  var myval;

  var cur_mode = document.proj_form.cur_dollars.value;

  if(cur_mode == new_mode)
   {
    return;
   }
  else if((cur_mode == 'd')&&(new_mode == 'kd'))
   {
     factor = "0.001";
   }
  else if((cur_mode == 'd')&&(new_mode == 'md'))
   {
     factor = "0.000001";
   }
  else if((cur_mode == 'kd')&&(new_mode == 'd'))
   {
     factor = "1000";
   }
  else if((cur_mode == 'kd')&&(new_mode == 'md'))
   {
     factor = "0.001";
   }
  else if((cur_mode == 'md')&&(new_mode == 'kd'))
   {
     factor = "1000";
   }
  else if((cur_mode == 'md')&&(new_mode == 'd'))
   {
     factor = "1000000";
   }

  document.proj_form.cur_dollars.value = new_mode;

  var cur_idx = document.proj_form.cur_idx.value;
  var available_slots = 13 - cur_idx;
  var td_name;
  var cell;
  var new_value;

  //Adjust dollar values for projections
  for(i=1;i<13;i++)
   {
    var myfield =  eval('document.proj_form.proj_'+i);
    if(myfield.value == '')
     {
      myfield.value = 0;
     }
    var myval = parseFloat(myfield.value) * parseFloat(factor);
    myfield.value = myval;
    if(i < cur_idx)
     {
      document.getElementById("actual_"+i).innerHTML = myval;
   }
 }
