Hi everyone,

sorry. But in my opinion actually simple, I have measurements in meters with for example:

1m -> space, unity, accuracy 1

2m --> space, unity, accuracy 1

3,2m --> space, unity, accuracy 2

3,4m --> space, unity, accuracy 2

4,56m --> space, unity, accuracy 3

6,57m --> space, unity, accuracy 3

So I have to specify in the units always a unit more to get the right (desired) rounding.

P.S. Thus, it is not a TC problem, but a mathematical problem.
