Is there a better way to ro开发者_C百科und decimals to 2 decimal places?

If you're interested in decimal places and therefore precise decimal values, you should typically be using java.math.BigDecimal to start with. You can then use Decimal.round or Decimal.setScale to round according to your exact needs.

DecimalFormat format=new DecimalFormat("#.##");
System.out.println(format.format(doubleValue));
