It's only necessary to ask a question once, by the way.
I'd perform this conversion using the NumberTool.
ie, once you have $numberTool installed in your context,
$numberTool.toNumber($count) <-- The result of this operation will be of
class Number

Note that tools like NumberTool are just plain old java objects, and you can
put them into your context in many ways, the easiest of which is.
context.put("numberTool", new
org.apache.velocity.tools.generic.NumberTool());
