0 equal to blank

[DouweMeer]

When the field is set as a number and the value for the field is a 0, than the boolean expression will state that the field with the value of 0 is both blank() as it is 0. 

I don't find this logical. Is this an old bug that was never been fixed and now everyone is working around and abusing it, or... is this intended?

Hi @DouweMeer, 

The same issue has been reported before internally: CRI 88868161. 

"In DAX, the comparison operator = performs equivalence comparison. Since 0 and BLANK are equivalent values, operator = returns true when comparing 0 to BLANK. Users can use DAX function IsBlank to detect BLANK values."
