private static DecimalFormat df2 = new DecimalFormat("#.##");
public static void main(String[] args) {
double input = 3.14159265359;
System.out.println("double : " + input);
System.out.println("double : " + df2.format(input)); //3.14
// DecimalFormat, default is RoundingMode.HALF_EVEN
df2.setRoundingMode(RoundingMode.DOWN);
System.out.println("\ndouble : " + df2.format(input)); //3.14
df2.setRoundingMode(RoundingMode.UP);
System.out.println("double : " + df2.format(input)); //3.15
}
