Question

I came across this problem, I have a number of type long which represents time (only seconds and miliseconds). I would like to display it for example like this 1,124 ms. I thought that simple division would do the job, so I tried this code

 long time = 2;
 System.out.println(((float) time) / 1000);

But when the number has only one digit like in the example above, it’s giving me 0,0020. So is there a way how to correct my formula or I have to manually cut the last zero?

Answer 1

Just use a formatting statement that makes it 3 decimal places

String.format("%.3f", floatValue);
