lookup to return larger value
Christobee wrote...
I have the following PSD data. In addition to the largest number less or
equal to the lookup value I would like lookup to also give me the smallest
value larger than or equal the lookup value on another cell. I would like
Lookup to give me the Size passed by 80 percent or less which is 19 and then
80% or more which is 25.

If your data values were in A2:B10, with both columns in ascending
order, the size passed by 80 or fewer would be given by regular
formulas
=LOOKUP(80,B2:B10,A2:A10)
or the array formula
=INDEX(A2:A10,MATCH(1,1/(B2:B10<=80)))
and the size passed by 80 or more would be given by the array formula
=INDEX(A2:A10,MATCH(1,1/(B2:B10<=80))+1)
If your range wasn't sorted, you'd need to use array formulas like
=INDEX(A2:A10,MATCH(MAX(IF(B2:B10<=80,B2:B10)),B2: B10,0))
and
=INDEX(A2:A10,MATCH(MIN(IF(B2:B10=80,B2:B10)),B2: B10,0))
