ice_raven Posted August 2, 2006 Share Posted August 2, 2006 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?

Giulio Toffoli Posted August 2, 2006 Share Posted August 2, 2006 There are several unuseful things in your expression, what do you want print starting from totalTime ? Giulio Link to comment Share on other sites More sharing options...
ice_raven Posted August 2, 2006 Author Share Posted August 2, 2006 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 '-'.

Giulio Toffoli Posted August 2, 2006 Share Posted August 2, 2006 Does 20.07 mean: a) 20 mins and 07 sec b) 20.07 mins c) 20h 07min ? Giulio Link to comment Share on other sites More sharing options...
ice_raven Posted August 2, 2006 Author Share Posted August 2, 2006 It means 20 minutes and 7 seconds.But if it gets sumed, you can get 20 minutes and a 95th of a minute and this is not wanted. Kind RegardsNeil Link to comment Share on other sites More sharing options...
Giulio Toffoli Posted August 2, 2006 Share Posted August 2, 2006 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.

If the amount is smaller than 60, then it does nothing.(I am using a shorthand if). I would just like to know how I can use operators (Like + - < > ...) in a variable expression in iReports.
