Yeah, doesn't look like NumberTool has the problem. Velocity must be
doing something funky with those # signs. Try defining those strings
with single quotes so that they aren't interpolated. Really, as a
general rule, if you don't need strings to be interpolated (parsed as
if they were mini-templates), then you should single quote them
instead of double quote.
$NT.format('#,##0.##','190.0')
And for the record, which version of Velocity is this with?
