Thank you, Mofi, for a very comprehensive reply !!

I am using the Sum selection command to sum up the values in 10,000 lines in column editing mode. This particular data column is basically this sum : 0.1+0.5+0.3+0.2+0.2+(9995*0.1) ... Can somebody please explain how / why UltraEdit sums up these values to 1000.8 0000000016 ? Where on earth does it ...
