Moving decimal places over in a double

So I have a double set to equal 1234, I want to move a decimal place over to make it 12.34

So to do this I multiply .1 to 1234 two times, kinda like this

Answer 1

you can try integer number representation

int i =1234;
int q = i /100;
int r = i % 100;

System.out.printf("%d.%02d",q, r);
