Double type for output

Question

I need the Celcius output to be two decimal places. When I enter
75 for Fahrenheit the result shows 23.88888888.
      //  Performs the conversion when the enter key is pressed in
      //  the text field.
      public void actionPerformed (ActionEvent event)
         double fahrenheitTemp;
        double celciusTemp;
         String text = fahrenheit.getText();
         fahrenheitTemp = Double.parseDouble(text);
         celciusTemp = (double)Math.round(fahrenheitTemp-32) * 5/9;
        resultLabel.setText (Double.toString(celciusTemp)); 
      }

Answer 1

You could use Class DecimalFormat.
          double number = 1.123456789;
          DecimalFormat df = new DecimalFormat("0.00");
          String formatted = df.format(number);
