Rounding

[Ships]

Good Morning,

April will be my first crack at the PE exam. I am taking the Naval Architecture/ Marine Engineering discipline however that has nothing to do with my question. Does the general rule of using 4 significant figures apply to the PE exam? I am concerned that if the correct answer is achieved via rounding and I do not (or vice versa) I may end up with a different answer than I am supposed to or wind up between two answer choices. I only see this being an issue with large numbers like moments of inertia etc..

Or will the answer chocies be such that it wont matter?

Thanks in advance.

Typically (unless there is a very precise, single, theoretical method to obtain the answer) answer choices are well separated - to the tune of 20-30% apart

Soil phase, 4 decimal places, curve geometry, you probably can round 5729.58 up to 5730 and have no issues.
