I have this code in velocity html
<html>
#set ($Total1 = 0.0)
#set ($Total2 = 3.0)
#set ($Total3 = $Total2 -$Total1)
$Total3
</html>
The $Total3 is not getting displayed. In fact the subtraction is not working. Can anyone please help me on this
I just tried that example in Velocity 1.6 and it worked fine.
Two possible things that might be causing problems.
(1) Your example is not copied correctly. If a dash is next to an identifier, it becomes part of the identifier. So this example would fail, since the "-" sign is actually part of the Total2 identifier.
(2) You are using a very old version of Velocity. Floating point numbers were legal syntax beginning with Velocity 1.5. (The current version is 1.7). Before that point, integers were the only number type allowed.
