var floatval = parseFloat(value)

OR

var floatval = value * 1

function dp(cost) {
return (cost*1).toFixed(2);
}

document.calcform.grandtotal.value = dp(((document.calcform.total.value*1))+((document.calcform.labor.value*1))+((document.calcform.inspection.value*1))+((document.calcform.trash.value*1))-((document.calcform.amount.value*1)));

***form****
<tr>
      <td width="10%" align="right">
      <div class="label">Inspection</div>
      </td>
      <td><input type="text" name="trash" value="<?php echo($trash); ?>" size=5 class="one_pixel_border" onChange="javascript: reCalculateValues(this.form)" /></td>                              </tr>

function dp(o) {

no that doesn't work...
now it's still dropping the zeros but then when i go to edit my fields it's giving me undefined for my calculations.

you can reference this question.

my trash field is just a number that gets inputed by the user then
js is using that value to do the grandtotal.
when i go into the edit form i would like for it to display as currency.
maybe that should be done with php?

I am not looking for points here.

I posted my answer for your previous question.

My answer has been proven to work (for last 2+ year), which takes of removing non-numberic from a value, rounding to nearest
decimal place.

<HTML>
<HEAD>
<TITLE>My Current Formatter</TITLE>
<STYLE>
</STYLE>
</HEAD>
<BODY>
<script language="javascript">
function formatCurrency(fld, curPrefix) {
num = fld.value;
//Get rid of any thing other than numbers and decimal places.
num = num.toString().replace(/[^0-9.]/g,'');
// Another safety check.
if(isNaN(num)) num = "0";

sign = (num == (num = Math.abs(num)));
num = Math.floor(num*100+0.50000000001);
cents = num%100;
num = Math.floor(num/100).toString();
if(cents<10) cents = "0" + cents;
for (var i = 0; i < Math.floor((num.length-(1+i))/3); i++) {
num = num.substring(0,num.length-(4*i+3))+','+
num.substring(num.length-(4*i+3));
}

// Comment next line you do not want 2 decimal places.
fld.value = ( ( (sign)?'':'-') + curPrefix + num + '.' + cents);
return (((sign)?'':'-') + curPrefix + num + '.' + cents);

// UnComment next line you do not want 2 decimal places.
//fld.value = (((sign)?'':'-') + curPrefix + num);
//return (((sign)?'':'-') + curPrefix + num);

}
