A very simple question, but I've been taught numerous ways to show working over the years. Just wondering which way is the simplest, quickest or most common way of showing it.

E.g.

Code:
10.12 (2dp)
10.1 (1dp)

10 (0dp)
10 (nearest whole)

etc.

I would stay away from the last two since if u had like a 0.65 you would round that up to 1 which is pretty far away from the answer. So best to stick to 1dp or 2dp (unless they specify)

Would 0dp suffice as a replacement for (nearest whole)?
