Hi,
Zope seems to evaluate expressions in an unconventional way.
No, its all alright ;)
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?
No, its integer :) 3/5 is 0, anything multiplicated with 0 will be 0. so 3/5*7 is 0 no matter where you set brackets :) Integer does not round, it only cuts off everything after the "." Eventually you want: a=3.0, b=5.0 and c=7.0 (even only one variable beeing "float" wuld be sufficient) Hth Tino Wildenhain
