hi. i got a problem. my Double $F{field} could be more than 2 decimal and to display it is no problem as i can use the pattern to format it. however, i need to sum the double $F{field} and the result should be exactly same as display in each field. my question is, how can i sum the $F{field} into a variable with exact 2 decimal??? i am currently using ireport 0.5.3
