How to round double / float value to 2 decimal points in Java
package xyz.jayakumar.test1;
import java.text.DecimalFormat;
public class RoundOf {
public static void main(String[] args)
{
double kilobytes = 1205.6358;
System.out.println("kilobytes : " + kilobytes);
double newKB = Math.round(kilobytes*100.0)/100.0;
System.out.println("kilobytes (Math.round) : " + newKB);
DecimalFormat df = new DecimalFormat("###.##");
System.out.println("kilobytes (DecimalFormat) : " + df.format(kilobytes));
