 The Xsum package is a Julia wrapper around Radford Neal's [xsum package](https://gitlab.com/radfordneal/xsum)
 for exactly rounded double-precision floating-point summation.  The [xsum algorithm](https://arxiv.org/abs/1505.05571) takes `n` double precision (`Float64` or smaller) floating-point values as input and computes the "exactly rounded sum" — equivalent to summing the values in *infinite* precision and rounding the result to the nearest `Float64` value.
