Floating point arithmetic has been added to the
very-stable-but-as-yet-not-released Velocity 1.5-dev version. If you
check out the SVN head, you can build and use it.
For previous versions of Velocity, i would recommend MathTool. :)

I just ran into a case where I wanted to do something like the following in
a template:
#set($fontSize1Percent = 85)
#set($fontSize2Percent = 0.75 * $fontSize1Percent)
When this didn't parse, I searched the velocity mail archives for
information on floating points, and found the the lengthy 2002 discussion.
The impression I got was that there was some interest in adding the ability
to specify floating point literals and to allow floating point arithmetic.
Was anything actually checked in for it? (As I recall the 1.4 release came
out quite a while after 2002.) If not, is the current best practice for
this sort of thing to use the MathTool class in the GenericTools
sub-project? With that, I could do something like:
#set($fontSize1Percent = 85)
#set($reduction = $math.div(75, 100))
#set($fontSize2Percent = $math.mul($reduction, $fontSize1Percent))
Thanks,
