We have installed Nintex workflow 2010 version 2.3.8.1. It seems like there is a bug with the round function. For some numbers with decimal .50 it is rounding to next integer but for some it is rounding back.
Example
- 5.50 gets rounded to 6
- 6.50 is rounding back to 6
- 0.50 is rounding back to 0
- 3.50 is rounding to 4
- 4.50 is rounding back to 4 etc..
