ATAN2 03-07-2020 11:38 AM

DAX doesn't have an ATAN2 function so I created one.

ATAN2 = 
    VAR __x = MAX('Table'[X])
    VAR __y = MAX('Table'[Y])
    VAR __atan2 = 
        SWITCH(
            TRUE(),
            __x > 0, ATAN(__y/__x),
            __x < 0 && __y >= 0, ATAN(__y/__x) + PI(),
            __x < 0 && __y < 0, ATAN(__y/__x) - PI(),
            __x = 0 && __y > 0, PI()/2,
            __x = 0 && __y < 0, PI()/2 * (0-1),
            BLANK()
        )
RETURN
    __atan2
