How to round up to 2 decimal places in java?
I have read a lot of stackoverflow questions but none seems to be working for me. i am using math.round() to round off. this is the code:
class round{
public static void main(String args[]){
double a = 123.13698;
double roundOff = Math.round(a*100)/100;
System.out.println(roundOff);
}
}
the output i get is: 123 but i want it to be 123.14. i read that adding *100/100 will help but as you can see i didn't manage to get it to work.
it is absolutely essential for both input and output to be a double.
it would be great great help if you change the line 4 of the code above and post it.
