Functions
double	eonc::exact::dot (const double *x, const double *y, std::size_t n)
	Round-to-nearest-even value of the exact sum of x[i] * y[i].
double	eonc::exact::orderedDot (const double *x, const double *y, std::size_t n)
	A fixed summation tree: four lanes (term i goes to lane i mod 4, each lane a left-to-right sum of rounded products), then (l0 + l1) + (l2 + l3).
double	eonc::exact::sum (const double *x, std::size_t n)
	Round-to-nearest-even value of the exact sum of x[i].
double	eonc::exact::sumStrided (const double *x, std::size_t n, std::size_t stride)
	Same sum for x[i * stride].

Variables
constexpr std::size_t	eonc::exact::kLanes = 4
