Description: Most of the time floating point arithmetic does
        approximately the right thing.  When adding sums or having
        products of numbers that greatly differ in magnitude, the
        floating point arithmetic may be incorrect.  This package
        implements the Kahan (1965) sum <doi:10.1145/363707.363723>,
        Neumaier (1974) sum <doi:10.1002/zamm.19740540106>,
        pairwise-sum (adapted from 'NumPy', See Castaldo (2008)
        <doi:10.1137/070679946> for a discussion of accuracy), and
        arbitrary precision sum (adapted from the fsum in 'Python' ;
        Shewchuk (1997)
        <https://people.eecs.berkeley.edu/~jrs/papers/robustr.pdf>). In
        addition, products are changed to long double precision for
        accuracy, or changed into a log-sum for accuracy.
