Talk:Pairwise summation

Comment
After reading this article, I could not tell *why* pairwise summation improves on the accuracy of ordinary summation. An estimation of the error is given, but without derivation, so I could not understand what makes this algorithm more accurate, esp. because it is mentioned that the number of additions is actually the same as ordinary summation. The article could be improved by explaining/giving some intuition for why this algorithm is more accurate. Polluxonis (talk) 18:50, 6 June 2020 (UTC)
