Decimal reducing

I try to reduce decimals with formatter, but it's no result, it continue show all double decimals into text field.
 
formatter = new DecimalFormat("#0.0");

                resist = DCC.getInstance().getTextresistEURUSD();
                rt = Double.parseDouble(resist);

                drt = (rt - askPx) * 10000;
                formatter.format(drt);

                dresist = String.valueOf(drt);
                DCC.getInstance().setEURUSD_resist(dresist);

Open in new window

Logically everything OK.
1. I get string;
2. Convert it into double;
3. Make calculation;
4. Deduce decimals;
5. Convert back to string and publish.
Please advice.

You should getbthe resulting string

StringBuffer s = formatter.format(drt);

String s1 = new String(s);

and then s1 would have less digits

You don't even need StringBuffer just
String s = formatter.format(drt);

This method does not change your double value - it just makes a string for you which is formatted
as you wish.
