DollarFormat rounding problem?

If you want better rounding with finer grain mods for up, down and even rounding, consider using the decimalRound UDF. After rounding, prepend the cosmetic $ symbol and use NumberFormat().

You could create your own UDF to leverage this:

<cfscript>
function DollarFormat2(num){
if (val(num) GT 0){
return "$" & trim(NumberFormat(decimalRound(num, 2, "up"), '999,999,999,999.00'));
} else {
return "-$" & trim(replace(NumberFormat(decimalRound(num, 2, "up"), '999,999,999,999.00'),'-',''));
}
}
</cfscript>

Using Trycf.com and choosing various CF flavors it seems this is normal across versions.  So it seems they expect you to round it then format it.
