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

You can printout a decimal encoded as an integer by divising by their factor (as a double)

int i = 10; // represents 0.10
System.out.println(i / 100.0);

prints

0.1

If you need to always show two decimal places you can use

System.out.printf("%.2f", i / 100.0);
