COMPLEX

In my recent quest to create or catalog as many DAX equivalents for Excel functions, this one was easy but brought back nighmares from P&A Circuits I and II...

 

COMPLEX = 
    VAR __Real = MAX([real_num])
    VAR __i = MAX([i_num])
    VAR __suffix = IF(MAX([suffix])="","i",MAX([suffix]))
RETURN
    SWITCH(TRUE(),
        __Real = 0 && __i = 1, __suffix,
        __Real = 0 && __i = -1, "-" & __suffix,
        __Real = 0, __i & __suffix,
        __i = 0, __Real & "",
        __i < 0 && __i = -1, __Real & "-" & __suffix,
        __i < 0, __Real & "-" & ABS(__i) & __suffix,
        __i = 1, __Real & "+" & __suffix,
        __Real & "+" & __i & __suffix
    )
