DIVIDE error ?
Straight from Microsoft's documentation: "Performs division and returns alternate result or BLANK() on division by 0."

if (ISERROR( blank()/0),1,2) - Return 2 NOT ERROR
if (ISERROR( 0/blank()),1,2) - Return 1 ERROR
How it possible to device Blank()/0 and not got error ? 🙂
Some kind new mathematics logic?
And DIVIDE(blank(),0,5)
i think all cases
1) x/0
2) blank/0
3) blank /X
4) X/blank
5)0/blank
6)blank/blank
Must return error and alternateresult ? or what ?
BLANK() and 0 are not quite the same thing. They are functionally the same in a lot of cases, but not always. However, it sounds like you want the DIVIDE function to treat BLANK() like a 0. In that case, wrap whatever is returning you a BLANK() in a COALESCE function:
COALESCE ( [measure returning blank], 0 )

If this post helps, please consider accepting it as the solution to help other members find it quickly. Also, don't forget to hit that thumbs up and subscribe! (Oh, uh, wrong platform?)but dividing by 0 should give an error always ? But no,
divide(blank()/0,1) and return Blank
divide(blank(),blank(),1) Return blank
and
divide(1,blank(),1) return 1
This is not mathematically and logicaly right
You can either work within the constraints of how Power BI actually works or just insist that it doesn't work the way your intuition says it should work. I don't know what to tell you. How division works with blanks overrides how division works with zeroes.
You do not have the ability to actually change how Power BI works to fit your intuitions better. (After all, you cannot actually have blanks in mathematics in the first place, right?)
