Convert a number to 2 decimal places in Java

Question

I want to convert a number to a 2 decimal places (Always show two decimal places) in runtime. I tried some code but it only does, as shown below

 20.03034 &g         


        

Answer 1

Try this: String.format("%.2f", angle);

Answer 2

try this new DecimalFormat("#.00");

update:

    double angle = 20.3034;

    DecimalFormat df = new DecimalFormat("#.00");
    String angleFormated = df.format(angle);
    System.out.println(angleFormated); //output 20.30

Your code wasn't using the decimalformat correctly

The 0 in the pattern means an obligatory digit, the # means optional digit.

update 2: check bellow answer

If you want 0.2677 formatted as 0.27 you should use new DecimalFormat("0.00"); otherwise it will be .27

Answer 3

Try

DecimalFormat df = new DecimalFormat("#,##0.00");

Answer 4

DecimalFormat df=new DecimalFormat("0.00");

Use this code to get exact two decimal points. Even if the value is 0.0 it will give u 0.00 as output.

Instead if you use:

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

It wont convert 0.2659 into 0.27. You will get an answer like .27.
