How do I round off a decimal number stored in double so that 12.80 becomes 13 and 12.20 becomes 12.

And if double returns me a value 12.2345456654 then rounding it off to two decimal places, how is it done?

Use class BigDecimal.

BigDecimal bd = new BigDecimal(12.2345456654);

bd = bd.setScale(2,BigDecimal.ROUND_HALF_DOWN);

//rounds to 2 decimal places
