Hi
Whan trying to use operators in a variable expression (like < > - + ) I get error messages when trying to compile the report.
The error message:
The operator > is undefined for the argument type(s) Integer, int
My expression:
((new Integer(new String($V{totalTime}.toString().substring($V{totalTime}.toString().indexOf("."), $V{totalTime}.toString().length()))) > 60) ? (new Double((new Integer(new String($V{totalTime}.toString().substring($V{totalTime}.toString().indexOf("."), $V{totalTime}.toString().length()))) - 60) & (new Integer(new String($V{totalTime}.toString().substring(0, $V{totalTime}.toString().indexOf(".")) + 1))))) : $V{totalTime})
Could anyone please help me with this?
Kind Regards
Neil

I have a field which shows minutes as a double. (eg 20.07 minutes)
Then I have a variable which sums all these numbers to get a total that displays for each group.
Simply adding these numbers don't work as you can get 20.95 minutes.
All the expression does is get the number after the '.' and if it's above 60, minus 60 from it and ad 1 to the minutes.
But it doesn't want to compile because I'm using '>' and '-'.

Hi Neil,
I understand the problem, but I can't figure out how do you perform the sum. I know that if you sum:
20.10 + 20.87 you get 40.97 (and you'll trnsform it in 41.37)
but what if you have:
20.50 + 20.59? you get 41.09 (and this can not be corrected because 09 is < than 60, but the correct number should be: 41.49, not 41.09)
So I suggest you to implement a custom Infrementer.
Attached there is a sample.

I would just like to know how I can use operators (Like + - < > ...) in a variable expression in iReports.
