Solved: Couldn't find a solution within the original server (CE 4.5.0), but upgraded the server to CE 5.2.0 and the problem was solved, input control data is displayed in the report as it was formatted in iReport, no truncation of decimals. I am guessing it is a jasperreports library issue, since the new server is using a newer library, the problem is finally solved. Hope this solutions helps anyone else with the same problem.
