How to calculate percentage points difference between two % measures?

[Pbiuserr]

Hello,

I have two measures which gives me output

Global % = 41,79 

Global % LY = 41,75

I would like to have point difference in 41.75 - 41.79 = 0.04, however the measure [Global %] - [Global % LY] gives me not correct output. Any idea how to get that?

@Pbiuserr Use ABS([Global %] - [Global % LY])? What are you getting currently?

Can't use ABS, it needs to show also if its decrease (-). It shows me - 0,0003

For instance:

Point change = 
VAR __year = SELECTEDVALUE (Calendar[Year])-1
VAR __month = 12
RETURN
[Global %] - CALCULATE ( [Global%] , FILTER ( ALL (Calendar),
Calendar[Year] = __year &&
Calendar[Month] = __month) )
