[CODE]

// The 0 symbol shows a digit or 0 if no digit present
    NumberFormat formatter = new DecimalFormat("000000");
    String s = formatter.format(-1234.567);  // -001235
    // notice that the number was rounded up
    
    // The # symbol shows a digit or nothing if no digit present
    formatter = new DecimalFormat("##");
    s = formatter.format(-1234.567);         // -1235
    s = formatter.format(0);                 // 0
    formatter = new DecimalFormat("##00");
    s = formatter.format(0);                 // 00
    
    
    // The . symbol indicates the decimal point
    formatter = new DecimalFormat(".00");   // pay attention here, that is what you want
    s = formatter.format(-.567);             // -.57
    formatter = new DecimalFormat("0.00");
    s = formatter.format(-.567);             // -0.57
