    private static DecimalFormat df = new DecimalFormat("0.00");
    public static void main(String[] args) {
        double input = 1205.6358;
      
        System.out.println("salary : " + input);
      
        // DecimalFormat, default is RoundingMode.HALF_EVEN
        System.out.println("salary : " + df.format(input));      //1205.64
        
        df.setRoundingMode(RoundingMode.DOWN);
        System.out.println("salary : " + df.format(input));      //1205.63
