Decimal conversion

I am trying to set decimal values,Below is my input string

String rate="1.000000000";

Converting to double:

Double converted=Double.valueOf(rate);
DecimalFormat format=new DecimalFormat("#.########"); //Setting decimal points to 8

System.out.println("ouput"+format.format(rate)); //Giving output as 1.

I dont understand how to do this,Any hints please.

Regards,

Chaitu

Firstly, you're passing the string rate to the DecimalFormat.format method. This will fail, you need to pass the converted object in.

When I tested your code with the above changes, I got 1.01 in the output. To format to 8 decimal places, follow Bala Rs comments. i.e. DecimalFormat format = new DecimalFormat("#.00000000");

# will not be displayed for 0, use 0 instead:

    String rate="1.010000000";
    Double converted=Double.valueOf(rate);
    DecimalFormat format=new DecimalFormat("0.00000000");       
    System.out.println("ouput "+format.format(converted));

Try

DecimalFormat format=new DecimalFormat("#.00000000");

and 

System.out.println("ouput"+format.format(converted));
