The range of double should be -1.79769313486231570E+308 to 1.79769313486231570E+308 (if using 64 bit java I assume..). There is also BigInteger / BigDecial that could be used, that supports even bigger numbers. That said, this is just what Java has to offer, what DHIS2 supports I do not know. -- Morten _______________________________________________ Mailing list: https://launchpad.net/~dhis2-devs Post to : [email protected] Unsubscribe : https://launchpad.net/~dhis2-devs More help : https://help.launchpad.net/ListHelp
