Ratings in half-steps

Hi,
Some music management programs use half-steps (5, 4.5, 4, 3.5, 3, etc). I just tried an advanced search with the filter defined as

Rating > 4 and Rating <= 5

and it grabbed the 4.5 and 5.0 rated files which is what I expected. The only problem is Rating doesn't allow for half-step filtering. I can only enter integers. Please allow for the half-steps so the filtering can be more precise with the underlying data.

Thank you.

FYI I'm using MusicBee. And I tried another advanced search defined as

Rating > 4 and Rating < 5

and it found nothing. So it doesn't read 4.5 as 4.5. Would the 4.5 rated files be seen as 5? That's what the searches suggest.
