Forget about this, java.text.NumberFormat is the answer.

Should be possible with class java.text.DecimalFormat (although much
more can be done with it)
Read

for examples.

You want to convert double or float to String.

You could use a NumberFormat to display the value to one decimal place.

fmt = NumberFormat.getNumberInstance();
fmt.setMaximumFractionDigits(1);

double myValue = 22.1999999998;
String valStr = fmt.format(myValue);
