Copyjava round double to 2 decimals
double roundOff = Math.round(a * 100.0) / 100.0;
// Or
double roundOff = (double) Math.round(a * 100) / 100;
// both have the same output.java round to 2 decimal
class round{
public static void main(String args[]){
double a = 123.13698;
double roundOff = Math.round(a*100)/100;
System.out.println(roundOff);
}
