+* Computes the sum of double-precision floating-point strided array elements using pairwise summation and alternative indexing semantics.
+*
+* ## Method
+*
+* -   This implementation uses pairwise summation, which accrues rounding error `O(log2 N)` instead of `O(N)`. The recursion depth is also `O(log2 N)`.
