It ain't pretty, but how about:

	[% MACRO commify(n) GET n.match('^([^.]+)').0.chunk(-3).join(',') _ n.match('(\..+)$').0 %]

or for European numbers:

	[% MACRO dotify(n) GET n.match('^([^,]+)').0.chunk(-3).join('.') _ n.match('(\,.+)$').0 %]

OK, maybe my suggestion's the hard way.  But it was fun to write!

Hope that helps,

Dave

P.S. For the record, this was my first try:

	[% MACRO commify(n) BLOCK; GET n.split('\.').0.chunk(-3).join(','); GET '.' _ n.split('\.').1 IF n.match('\.').0; END %]

I didn't benchmark to see which was faster.
