Sorting the list by absolute value and then summing from smallest to largest would be most accurate way to do this. I didn't have this luxury in the 34S. It lacks the memory to store the terms but for newRPL, you've got them all in the list already.

Quote:While using REVLIST is fine, it's much slower than just adding in reverse order.

Wouldn't the time for the floating point additions far outweigh the time to reverse the list???
