How to set decimals to only 2 digits in Doubles?

Question

In my response i am getting the value as 80.00000

DecimalFormat df = new DecimalFormat("##.##");
TextField.setText(df.format(Double.parseDouble(custom.getValue())));

My problem is i am getting 80.000, i am doing a parseDouble which will return a primitive double type and i am doing a format to this double to 2 decimals.

Why am i getting 80 instead of 80.00?

I changed my way and tried with this.

TextField.setText(String.format("%2f",Double.parseDouble(custom.getValue())));

Now i am geting 80.000000 instead of 80.00

Should be "%.2f" instead of "%2f"

TextField.setText(String.format("%.2f",Double.parseDouble(custom.getValue())));

you forget to add the .

The first example should be:

DecimalFormat df = new DecimalFormat("##.00");

Otherwise any non significant fractional digits will be suppressed.

java.text.NumberFormat is a good alternative

final NumberFormat nf = NumberFormat.getInstance();
nf.setMinimumFractionDigits(2);
nf.setMaximumFractionDigits(2);
nf.setGroupingUsed(false);
System.out.println(nf.format(123456789.123456789));

Change %2f to %.2f in the String.format parameter.
