In my recent quest to create or catalog as many DAX equivalents for Excel functions, was able to build upon my work with IMAGINARY and IMREAL to get this one:
IMCONJUGATE =
VAR __Complex = [COMPLEX]
RETURN
SWITCH(TRUE(),
__Complex = "i","-i",
__Complex = "j","-j",
__Complex = "-i","i",
__Complex = "-j","j",
FIND("i",__Complex,,-1) = -1 && FIND("j",__Complex,,-1) = -1,__Complex & "", // handle only real numbers
FIND("+",__Complex,,-1) <> -1,SUBSTITUTE(__Complex,"+","-"), // handle positive i
FIND("-",__Complex,2,-1) <> -1,SUBSTITUTE(__Complex,"-","+",2), // handle both negative real and negative i
SUBSTITUTE(__Complex,"-","") // handle just negative i
)
The real question in my mind though is, why; if there is a loving God, does that image exist? I mean, some things you just can't unsee. I've heard my son talk about cursed images and I believe this qualifies...
