How to round the double value to 2 decimal points? [duplicate]

Answer 1

This would do it.

     public static void main(String[] args) {
        double d = 12.349678;
        int r = (int) Math.round(d*100);
        double f = r / 100.0;
       System.out.println(f);
     }

You can short this method, it's easy to understand that's why I have written like this.

Answer 2

I guess that you need a formatted output.

System.out.printf("%.2f",d);
