lookup to return larger value
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. Size (mm) % Passing 1.7 0.16 2.8 0.47 4.75 1.25 6.7 2.04 8 3.61 10 11.44 13.2 38.09 19 72.57 25 94.51 |

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)) |

I get and Error message with both of your formulas for some reason the
formulas contain invalid data "Christobee" wrote: I have the following PSD data.

It works. Very helpful. Thanks Grove!
