If you use EXACT it is likely to report the floating point errors you are finding. Try ABSOLUTE is it should ignore small differences.

But for some reason even though I have the same values the diff is calculated as a E value ( eg: 28.4-28.4=3.552714E-150). I know this is a place for data step questions but this happens even if I do a difference in the datastep. As of now to keep rolling I created an array that looks at each record and variable with "E" and changed to "0". But is there a way/function that I need to incorporate to over come this issue. <BR /> <BR /> Regards,<BR /> Addy Wed, 28 Jul 2010 18:45:01 GMT https://communities.sas.com/t5/SAS-Programming/Dealing-with-E-values/m-p/56888#M12180 deleted_user 2010-07-28T18:45:01Z https://communities.sas.com/t5/SAS-Programming/Dealing-with-E-values/m-p/56889#M12181 Floating point error is annoying but it happens. Use C=fuzz(A-B) .
