Question

I have some calculation like this

public class Florida {
public static void main(String arg[]){

    double value = 9223372036854775807l;
    double ans = 0;
            ans = ans + value * 2.00 /1000;
    System.out.println("Hello : "+ans);
  }
}

but I am getting answer like this

Hello : 1.8446744073709552E16

and I need in simple digit format.

Answer 1

Use printf() with %f:

System.out.printf("Hello : %f\n", ans);

You can change the number of significant digits by tweaking the format specifier; for example, the following will just print out the integer part:

System.out.printf("Hello : %.0f\n", ans);
