You can use Math.round to round numbers. Check all the features of the Math class here:

Good luck.
Cheap and dirty rounding trick: add 0.5 and convert to int. Fails for negative numbers, of course. Think about what you'd do to make it work for negatives as well - and then go ahead and use the library method.
(It's always a good idea to use a library method where they are available, but it's also well worth the trouble to think about how you'd solve it yourself if you have to)
I google it and I find method that help me with it
thanks all for help =)
