Hi, We have a Form that accepts many fields for user to Input. Here is the problem... Example: Assume 2 fields qty (for getting quantity from the user) and unitprice ( accepts unit price from the user). Inside the servlet... String unitprice = req.getParameter("unitprice"); double unitprc = Double.valueOf(unitprice).doubleValue(); String qty = req.getParameter("qty"); int quantity = Integer.parseInt(qty); double total=0.00 total = quantity * unitprc; When this total field is printed, it gives the output with single precision (decimal) like 25.0 etc. Here is an example: If qty=5 and unitprice=4.0 or 4.00 or 4 the total reflects only 20.0 Actaully, the output is expected to be something like 20.00 (i.e with 2 decimal places) Any help is appreciated. Thanks, Suresh Selvaraj

I think it is due to multiplication of int and double. Try as total = (double) quantity * unitprc

Hi All, Thanks very much for your reply. I tried using java.text.DecimalFormat class and I was able to get the required output. Thanks very much. Suresh Selvaraj
