Problem with JFormattedTextField - Number field

Hey!

I'm having problem with entering numbers after decimal point. I 've set
two numbers after decimal point. when I add first time it's working.
When try to override it takes third number & rounding it off and adding
it.

If I enable override mode enable when I entering number reaches cmmma
(,) with out problem but afterwards it takes next two digits after
decimal point addes with entered number.

I tried my best to solve it. please someone help me to sort out this
problem..

I've added my code here you can test and give me some idea..

public class NumberCellEditor{
   DecimalFormat numberFormat;
   JFrame frame;
   JFormattedTextField text,text1;
   JPanel panel;

public void create(){

       text=new JFormattedTextField();
       text1=new JFormattedTextField();

      numberFormat = (DecimalFormat) NumberFormat.getNumberInstance();

      numberFormat.setDecimalSeparatorAlwaysShown(true);

     numberFormat.setMinimumFractionDigits(2);

      NumberFormatter numFormatter = new
NumberFormatter(numberFormat);

      numFormatter.setAllowsInvalid(false);
      numFormatter.setFormat(numberFormat);
      //numFormatter.setOverwriteMode(true);

      text.setValue(new Float(0.0F));
      text.setFormatterFactory(new
DefaultFormatterFactory(numFormatter));
      text.setHorizontalAlignment(JTextField.TRAILING);

    }

public void createComp(){
   frame=new JFrame(" TEST 2");

   panel=new JPanel();
   panel.setLayout(null);
   create();
   text.setBounds(100,100,100,30);
   text1.setBounds(100,200,100,30);
   panel.add(text);
   panel.add(text1);

   frame.getContentPane().add(panel);
   frame.setSize(300,300);
   frame.setVisible(true);

   NumberCellEditor n=new NumberCellEditor();
   n.createComp();
