Objective: I have an existing rule that produces a decimal proportion, BUT I need it to produce the percentage and round it to the nearest whole number. This is my current rule:

Attempts:
I tried changing the smart value to this {{issue.OrigAllowed.format(".##")}} just to round it but it did not work. So I did not even attempt to covering it to a percentage. Which I don't know if I can even do that or would that have to be a separate rule?
