  "Description": "Sums of double-precision numbers computed exactly and\nrounded once, so the result is the correctly rounded true sum\nand does not depend on the order of the elements, the platform,\nor whether R was built with long doubles. Built on the small\nand large superaccumulators of Neal (2015)\n<doi:10.48550/arXiv.1505.05571>. Provides exactly rounded sums,\nmeans, cumulative sums, dot products and norms, row, column and\ngrouped sums, accumulators that can be built in pieces and\nmerged across processes, and a registered 'C' interface for\nother packages.",
