How to limit decimal places using printf in Java?

I'm trying to truncate to the third decimal point using printf in Java, but I keep getting to only the second decimal point. Here's the line of code where I was attempting this:

System.out.printf("The speed in ft/sec is %6.2f\n", time);

Try this:

System.out.printf("The speed in ft/sec is %6.3f\n", time);

The above will round to three decimal places (not "truncate" them). The only difference is in the value after the dot.

Try %6.3f instead. the format is

%(before).(after)(type)
    6         3    f

    6 -> 6 digits before the decimal
    3 -> 3 digits AFTER the decimal
