Thanks Bob and Allan for answering my question on summing lists. I have another question. Suppose I have a sorted list (using union) of rational numbers. Is there a function that calculates those rational numbers to a given decimal position, preferably a listable function so I don't have to operate in a loop? Also, suppose that I have done that and now have a list of (still sorted, I think) decimal representations. Is there a quick way to remove any duplicates in this list, or do I have to use a loop and test equality each part of the list to the next part? Thanks again! I really appreciate it! Alan
