[Zope] dtml-var "fmt" question

hi everyone, maybe someone has done this before and could advise me: i want to format a floating point variable so it comes out using the european decimal point notation. so instead of 12.5 i would like it to say 12,5 etc. the DTML guide offers some nice built-in formats (like "dollars-and-cents"), i wonder if someone had an idea about maybe doing a "euros-and-cents" one, with the right decimal punctuation and a euro sign ;) Jens Vagelpohl P.S.: at this point i wonder why i ever wrote static HTML... :P
