Hi, I am trying to apply the Union function to a list of real numbers, in which many duplicates occur. However, small differences between the numbers cause some of the duplicates to be retained instead of discarded. Suppose the list of real numbers is called k, my present work-around is as follows: Union [ Rationalize [ k, 10^-6 ] ]. This does discard the duplicates. Is there a better method?
