Format field to currency
Looking to format a field to US dollar currency style? This function will round your value to the nearest tenth position, and add a dollar sign.
The following code is a JavaScript function. Simply pass your numeric value to this function and it will format it for you:
<script language="javascript">
function currency( num )
{
var prefix = "$";
var suffix = "";
if ( num < 0 )
{
prefix = "($";
suffix = ")";
num = - num;
}
var temp = Math.round( num * 100.0 ); // convert to pennies!
if ( temp < 10 ) return prefix + "0.0" + temp + suffix;
if ( temp < 100 ) return prefix + "0." + temp + suffix;
temp = prefix + temp; // convert to string!
return temp.substring(0,temp.length-2) + "." + temp.substring(temp.length-2) + suffix;
}
</script>
Always working hard!!
