For those of you who use the metric system:
Does your computer give you the depth to tenths of a meter or whole meters?
When doing calculations do you use or require precision to tenths of a meter?
My computers (Suunto Zoop and Shearwater Petrel) gives the depth with a precision of tenths of a meter like "34.5"
When doing dive related calculations I just keep it simple and round up ( or dow, depending on what gives me a bit of safety margine) to nearest whole meter.
