match nearest

bogu0001 · #1 (**permalink**) 02-12-2009

Hi,

I'm trying to find the nearest match between two columns of numbers, e.g.

1,1
10,8
30,50
20,100

and the search could be e.g. 20,20

returning 10,8 - i.e. 20-10 = 10 and 20-8 = 12 totalling 22, and hence being the nearest match.

any ideas?

thanks a lot,
