I dive metric, my stops are all multiple of 3 m and my tanks have the real MODs, not rounded ones, as I understand MODs as maximum operation depth, not mandatory other-gas depth ;) But obviously I understand that having the MOD equal to some deco stop might seems less confusing. Truncating sounds more conservative but actually I bet that if your dive plan gets unsafe because of half a meter on a deco stop or worst half a foot you have other problems not rounding related so rounding seems to me as the right thing to do.
