Why sum() differs between machines | One rounding, at the end | Special values | Sums in pieces, and across processes | From C, in other packages

zuexact: Exactly Rounded Sums, Means and Dot Products
Sums of double-precision numbers computed exactly and rounded once, so the result is the correctly rounded true sum and does not depend on the order of the elements, the platform, or whether R was built with long doubles. Built on the small and large superaccumulators of Neal (2015) <doi:10.48550/arXiv.1505.05571>. Provides exactly rounded sums, means, cumulative sums, dot products and norms, row, column and grouped sums, accumulators that can be built in pieces and merged across processes, and a registered 'C' interface for other packages.
