Recently, I found an issue in a Dashboard because initially has a column as "Whole" number instead "Decimal" from Excel file.
Then I notice and ask me. Why have the same icon for different number?
The idea is change the green icon to two different ones to be more easy to discover errors by wrong Data Types.
Right now I have to do a right click and see with a tooltip if It is in the correct Data Type.
This difference is already implemented in Date and Date and Time Data Types
