Print Integer with 2 decimal places in Java

Question

in my code i use integers multiplied by 100 as decimals (0.1 is 10 etc). Can you help me to format output to show it as decimal?

Answer 1

I would say to use 0.00 as format:

      int myNumber = 10;
      DecimalFormat format = new DecimalFormat("0.00"); 
      System.out.println(format.format(myNumber));

It will print like:           

      10.00

The advantage here is:

If you do like:

      double myNumber = .1;
      DecimalFormat format = new DecimalFormat("0.00"); 
      System.out.println(format.format(myNumber));

It will print like:

      0.10
