There are some problems with the inward rounding. Here are the step of the problems.
1. Normal dual dimension works
2. I need to use "LIMIT" on a dimension. Sometimes, SW will make problem of the second unit
3. In order to solve the problem in step 2, I need to disable the inward rounding. Most of the time it works
4. Some time the step 3 solve the second dimension problem, but it make the first dimensions many 000000000000000s
How to fully solve this kind of issue? Please see the attached pictures.
