Ok, this might get me somewhere. I did some testing like so, but the classname is always black:
<$set name=number value=-5> <$set name=cssclassname filter="[<<number>>sign[]match[-1]then[red-bold]else[black]]"> <span class=<<cssclassname>>><<number>></span> </$set> </$set> There's also no guarantee if I go down this road that the text from the tiddler where I use formulas to make a calculation will be parsed as its resulting number, rather than just a weird string.
