Question: After how many digits are people typically rounding values? There are (extremely) minor rounding errors in my calculations. Is this part of the specification too? MLCad seems to round after 6 digits.

Not part of the spec but the standard is 4 decimal places for rotation matrices. To prevent rounding errors, in LDDP I use full floating point precision though all the math and then round as the final step before displaying the line.
