What does "correct" mean?

I've been asking this question for a long time, and never could figure out who to direct it to for a definitive answer, so here's a try:
The AP exam exam asks for answers "correct to 4 (I think) decimal places."
Does this mean to round the answer to nearest tenthousandth? (And, why not say it that way?) But, if someone asks for pi correct to 4 decimal places, the expected answer is 3.1415, which is of course *not* rounded. Are you with me?
Can any of you AP readers/writers rule on this? Perhaps the readers give credit whether the answer is correctly rounded or not? Hopefully it's a trivial issue (that's what I've been assuming for all the years that calculatorstyle answers have been a possibility)
