Use the JJS command line or script runner
Set the domain value to 0.2 in your JJS input or variable
If the domain is defined as a range, use 0 to 0.2
If the domain is a step size, set the increment to 0.2
If the domain is a threshold, compare against 0.2
If the domain is a decimal field, enter 0.2 exactly
Verify the domain format required by your specific JJS workflow
Run the script and confirm the domain is interpreted as 0.2
