Validation Error for Negative Values in Power Query

Hi, 
 
I have the following error message below when trying to refresh my Data Table in Power Apps. 
 
I have a custom variance column that outputs negative values.
 
How do i get the query to accept the negative values?

I have tried to use the rounding function this was unsuccessful 
 
Note the column is a custom column that calculates two values together. 
 

Thank you

Here's a similar thread with a solution. Looks like you need to change the data type in Power Apps.
