Find nearest value

[SLHayden]

I am trying to find a way to identify the nearest value to a ref number. I am using
=INDEX(AU8:AU28,MATCH(MIN(ABS(AU8:AU28-T29)),ABS(AU8:AU28-T29),0))

The problem I am having is in situation where a list will contain values like 54 and 58, and the REF VALUE is 56; both values have and absolute value difference of 2. The formula will only return the number that is closest but not higher. Is there a way identify both.

For simplicity, let's assume that A2:A10 contains the data, and C2 contains the reference value. Try...

D2, confirmed with CONTROL+SHIFT+ENTER:

=MIN(ABS(A2:A10-C2))

E2, confirmed with CONTROL+SHIFT+ENTER:

=SUM(IF(ABS(A2:A10-C2)=D2,1))

F2, confirmed with CONTROL+SHIFT+ENTER, and copied to F3:

=IF(ROWS(F$2:F2)<=$E$2,INDEX($A$2:$A$10,SMALL(IF(ABS($A$2:$A$10-$C$2)=$D$2,ROW($A$2:$A$10)-ROW($A$2)+1),ROWS(F$2:F2))),"")

A2:F10:
