Java: double: how to ALWAYS show two decimal digits

Question

I use double values in my project and I would like to always show the first two decimal digits, even if them are zeros. I use this function for rounding and if the value I print is 3.47233322 it (correctly) prints 3.47. But when I print, for example, the value 2 it prints 2.0.

public static double round(double d) {     BigDecimal bd = new BigDecimal(d);     bd = bd.setScale(2, BigDecimal.ROUND_HALF_UP);     return bd.doubleValue(); } 

I want to print 2.00!

Is there a way to do this without using Strings?

EDIT: from your answers (which I thank you for) I understand that I wasn't clear in telling what I am searching (and I'm sorry for this): I know how to print two digits after the number using the solutions you proposed... what i want is to store in the double value directly the two digits! So that when I do something like this System.out.println("" + d) (where d is my double with value 2) it prints 2.00.

I'm starting to think that there is no way to do this... right? Thank you again anyway for your answers, please let me know if you know a solution!

Answer 1

You can use something like this:

 double d = 1.234567;  DecimalFormat df = new DecimalFormat("#.00");  System.out.print(df.format(d)); 

Edited to actually answer the question because I needed the real answer and this came up on google and someone marked it as the answer despite the fact that this wasn't going to work when the decimals were 0.
