ironicly, none of these are best solved with fmt ;-)

<dtml-var x null=""> (maybe)
<dtml-if x><dtml-var x></dtml-if> (definitely)

<dtml-if "x>0"><dtml-var x><dtml-else><dtml-var "-x"></dtml-if>

Personally, I'd recommend you get the online Zope book and learn ZPT instead.
The above examples become:

<tal:x content="python:x.strftime('%d-%m-%Y')">31-12-2001</tal:x>

 >   I need to format 0.00 as nothing (leave blank)

<tal:x content="x"
        condition="x">0.00</tal:x>

 >   I need to format -2,782.50 as 2,782.50 (absolute)

<tal:x content="python:abs(x)">2,782.50</tal:x>

cheers,
