Hi,
Zope seems to evaluate expressions in an unconventional way. Say I have three properties, a=3, b=5, c=7 set in a Folder. In a DTML Document I tried to say <dtml-var "a/b*c"> and got result 0. The expression was evaluated as a/(b*c) and rounded off. Is not the expression supposed to be evaluated as (a/b)*3? The result is not correct still if we put it this way: <dtml-var "(a/b)*3">. I still got 0 as the result. Did I miss anything fundamentally or is this a, bug?
You have to convert it from integer to float. Try: <dtml-var "(_.float(a)/b)*c"> Though you're rigth, you need the parenthesis for the correct evaluation. hth, Thomas
