Fix Number Value inputs in workflow designer
There seems to be a problem with the regular expression that stops you from adding text to a number field. I can't enter any number with a 0 after the decimal point. So a value like 1.02 can't be entered.

This idea is currently supported in Nintex Workflow Cloud. As our next generation workflow orchestration platform, we recommend customers to move to NWC. Learn more about NWC and the migration tool here.

I had this same problem and went back and forth with support trying to explain it was probably a Javascript validation bug removing the zero. You can however type in the number without the zero (1.2) and then add the zero in afterwards (1.02).
