    IMAGINARY

    ‎05-03-2020 05:56 PM

    In my recent quest to create or catalog as many DAX equivalents for Excel functions, this one is a bit brute force but I think I got all of the scenarios.

     

    IMAGINARY = 
        VAR __Complex = [COMPLEX]
    RETURN
        SWITCH(TRUE(),
            __Complex = "i" || __Complex = "j",1, // handle i
            __Complex = "-i" || __Complex = "-j",-1, // handle -i
            FIND("i",__Complex,,-1) = -1 && FIND("j",__Complex,,-1) = -1,0, // handle only real numbers
            FIND("+",__Complex,,-1) <> -1 && LEN(__Complex) - FIND("+",__Complex,,-1) = 2,1,
            FIND("+",__Complex,,-1) <> -1,MID(__Complex,FIND("+",__Complex)+1,LEN(__Complex) - 1 - FIND("+",__Complex)) + 0, // handle positive i
            FIND("-",__Complex,2,-1) <> -1,MID(__Complex,FIND("-",__Complex,2)+1,LEN(__Complex) - 1 - FIND("-",__Complex,2)) * -1, // handle both negative real and negative i
            MID(__Complex,FIND("-",__Complex)+1,LEN(__Complex) - 1 - FIND("-",__Complex)) * -1 // handle just negative i
        )
