HI
who can explain me
DIVIDE(blank(),0,5) - return BLANK
DIVIDE(0,blank(),5) - return 5
if (ISERROR( blank()/0),1,2) - Return 2 NOT ERROR
if (ISERROR( 0/blank()),1,2) - Return 1 ERROR
Why blank()/0 is not error ? and why is divide return BLANK ?
Straight from Microsoft's documentation: "Performs division and returns alternate result or BLANK() on division by 0."

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 )

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?)

There's no point in arguing.
If it is necessary to get a value other than BLANK as a result of division -
function is not suitable.
If a formula or procedure works incorrectly, it is usually fixed by the developers.
The recommendations to always use DIVIDE instead of IF is not 100% correct
So the performance is lost 😞 unfortunately
In addition, if divide(blank()/0,1) and divide(0/blank(),1) had given the same result, I would even agree with you, but unfortunately the results are different . Right ?
I disagree with you that it works incorrectly, but I agree with you that "arguing" would be a waste of time so have a great day! 😄
