Your best bet is to ask on the velocity-user@jakarta.apache.org mailing 
list, to which I've cc'd this message.

Internally, NumberTool just references NumberFormat:

http://java.sun.com/j2se/1.4.2/docs/api/java/text/NumberFormat.html 

You can also "cheat" and treat the result of 
"$number.getNumberFormat('number', $number.getLocale()))" as a 
DecimalFormat, although this may fail for releases other than Velocity 1.3.1 
and Velocity Tools 1.1.

#macro (formattedCpac $value $valueIfEmpty)
#set ($cpacFormatter = $number.getNumberFormat('number', 
$number.getLocale()))##
${cpacFormatter.setMinimumFractionDigits(5)}##
${cpacFormatter.setMaximumFractionDigits(5)}##
#if($value)${cpacFormatter.format($value)}#else${valueIfEmpty}#end#end
