How to avoid Key Figure Time Rounding or Decimal Cut in Report

Hi,

I'm looking into how to avoid my new key figure to do rounding/remove the decimals, but haven't figured out how to get it to work.

I've created a new key figure "actual actual work" it is Recorded Time - Absence

As you can see from the picture below total hours of absence is equal to 13,5 hours and record time is 21 hours. My new key figure shows 8 h and not 7,5 h which would be the correct number.

I have tried several different approaches

[Recorded Time] - [Absence]

ABS([Recorded Time]) - ABS([Absence])

ABS([Recorded Time] - ([Absence])

and from the picture below I'm trying to use the calculated Absence(1) key figure, not sure if this is a custome or standard SAP.

Any help would be appreciated.
