"DecimalFormat"

[Rohit Prakash Khare]

Hi,
In my program I have a double variable, which displays result as "1.436555578". I want to restrict the display to two decimal places like "1.43".
How to do so ? Please illustrate with small code.

Hi Rohit,
Take a look at the following Method. The method takes a given prices and formats it.

/**
 *Description: 
 *formats price as #.00.
 *if invalid price is passed, 
 *              returns without change. 
 *e.g., 12.771 will be returned as 
 *              12.77 and abc will be returned as 
 *              abc.
 *
 * @param price the price to be formatted
 *
 * @return String the format price
 */
 private String formatPrice (String price) { 
     String formatedPrice = "";
     try {
      double dPrice = Double.parseDouble(price); 
      
         java.text.NumberFormat f = new java.text.DecimalFormat("0.00"); 
     
         formatedPrice = String.valueOf(f.format(dPrice)); 
    }
    catch (Exception e) {
    formatedPrice = price;
    }
    
    return formatedPrice;
  
} // $ End formatPrice ()

Hope this helps.
Thanks,
Tom
