I suspect the issue is a precision issue with tth values displayed. I suggest that you change the format of the E and D columns to display more than 4 decimal places. This may expose where the issues are. You may also be able to resolve the issue by rounding the values to 4 decimal places in your formula. i.e
If(
Abs(
Round( :e[Sequence( 1, 55058, 1, 1 )], 4 )
-Round( :e[Sequence( 2, 55058, 1, 1 )], 4 )
) == Round( :d[Sequence( 1, 55058, 1, 1 )], 4 ),
:f = .,
:f = :e
)
