double d = 24.61835496354822;
DecimalFormat f = new DecimalFormat("##.00");
System.out.println(f.format(d));

Either use System.out.printf("%.2f", val);` or

DecimalFormat df = new DecimalFormat();
df.setMaximumFractionDigits(2);
System.out.println(df.format(decimalNumber));

new DecimalFormat("##.##").format(number);

Try This :

import java.text.*;  
 class Decimals {  
  public static void main(String[] args) {  
    float f = 24.61835496354822f;  
    DecimalFormat form = new DecimalFormat("0.00");  
    System.out.println(form.format(f));  
  }  
}

You could use a simple string format like:

String.format("My value is: %.2f",  myFpVal));

If you just want the value, you can make your format string contain just the format instruction like:

String.format("%.2f",  myFpVal));
