I experience that Powerbi returns a positive value where it should be negative when starting with a negative number.
Example:
Value1 : -0,001010
Value2 : 0,000011
Value1 - Value2 = -0,001010 -0,000011 returns 0,001021...
It is almost correct exept that it should be a negative number returned not a positive.
In my dax example underneath, it is wrapped in Averagex to catch if the user as selected a range. In reality the user is only selecting two numbers.
My dax example:
I am working with measurements where the instrument have an accuracy of 6 digits.
@Anonymous ,
I have made a test but couldn't reproduce your issue. The result is negative on my side. Please make sure power bi desktop has been updated to the latest version.
