@tubetime it’s 2.56, äktschually!

@tubetime Shouldn't that be 2.56?

@tubetime @adistuder @brainwagon If the units are discrete (increments of 0.01 cm) then there are 256 possible values of length from 0.00 cm up to 2.55 cm. 2.56 cm would be 0x0100.

If the units are continuous (not integers) then it would range from 0.00 ≤ length < 2.56, so length up to but not including 2.56 cm. In this case, answering "how many mm are there in an 8-bit inch" is harder because there are infinitesimally less than 256, and also sort of inaccurate because that's not really 8 bits.

@tubetime am dealing with label printers at work that have 203dpi or 8dpmm ... but actually 7.99dpmm and it does my head in ... but given each label is 66mm and the error for finding the edge for the next is 0.5-2.0mm I think it is unlikely to matter much over that length ...
