Converting from decimal pounds to pounds and ounces is a data display issue.
I think the most useful solution would be a UDF. Then you can use it
whenever you need to do this. The benefit is that you don't have to touch
your original data -- the 8.16 still remains afterwards.
<cfscript>
function poundsAndOuncesFormat(value) {
var returnString = "";
var pounds = int(value);
var ounces = (value - pounds) * 16;
ounces = round(ounces * 100) / 100; // round ounces off at 2
decimal places
if ( pounds )
returnString = pounds & " lb";
if ( ounces )
returnString = listappend(returnString, ounces & " oz", " ");
return returnString;
}
</cfscript>
<cfoutput>#poundsAndOuncesFormat(8.16)#</cfoutput>
