input 12.5 after DecimalFormat's ROUND_HALF_EVEN setScale, can get what?:)
hi, everybody.
i think ROUND_HALF_EVEN means when i input 12.5, after the process of setScale(0,BigDecimal.ROUND_HALF_EVEN), i can get 13.
but in fact, the out put is 12....
so. i tried 13.5....i get 14( that's what i want...)
and i tried more, all the result are right but 12.5..........
and i tred this sql in oracle
select round(12.5) from dual;
i got 13 now....
it seems that something wrong in my program or jdk. but i can not find out.
so i came here for your help...thanks a lot...
output......................
