Comparing 2 sets of data

[mattkbn1]

Hi I was hoping someone could help me compare 4 columns of data. For my data I am just comparing the outputs of two programs (for example the x-y coordinates of a map). So in columns A & B I have the x-y coordinates from 1 program and columns C & D I have the x-y coordinates from another program and I want to compare to see which ones match. There is also some error in the coordinates as one program is more sophisticated than the other. So for example here is some of the data:

As you can tell the data on the left is much more detailed than the one on the right, but I still need to compare them for similarities. Any help would be greatly appreciated.

In your example none of them match.
Since you say the numbers are more detailed
can you supply some data where the numbers are different but YOU consider them to "match"?

Oh I'm sorry, there are thousands of rows of data and there should be an eventual match on the left side with the ones on the right. It's just the data in columns A & B are much more precise and find many more points. I should have specified that the columns A & B have many more x-y coordinates than columns C & D. But that is what I am trying to determine; So for columns A & B there are 10,000 different points and for columns C & D there are only about 5,000 (because one program was more precise than the other). I just want to see which points these two sets of data have in common...
