Hi there.
I just noticed that when add 2 variables defined as length (mm), the resut increase the value of 0.00000000000006.
Can someone help me figure out why?
As you can see from the picture below, adding the unit after the addition removes the error.
Result Format
Format: General
Number of decimal places: 17
Show trailing zeroes: yes
Format units: yes
Simplify units when possible: yes
