The Java backend retains two decimal places

The Java backend retains two decimal places

1. (double) (Math.Round (sd3*10000)/10000.0);

this keeps the 4-bit

( Double) (Math.Round (sd3*100)/100.0);

this keeps the 2 bits.



2. Another approach
import Java.text.DecimalFormat;

DecimalFormat df2 = new DecimalFormat ("###.00");

DecimalFormat df2 = new DecimalFormat ("###.000");

System.out.println (Df2.format (Doube_var));

The first one is 2 bits and the second is 3 bits.

3 new JDK
String.Format ("%10.2f%%", Doube_var);
