Hi,
Well I spotted the same problem, and before creating a post I verify for existing ones, and found this post.
In_Number is mandatory
DecimalDigits is not mandatory and have "2" as default
Out_FormatedNumber will be DecimalDigits value
This problem only occur when the client action is used as Function
And this works as intended on Traditional (Show "2" instead of "0")



Indeed this seems to be a BUG
