impl f64x2
[src]

🔬 This is a nightly-only experimental API. (stdsimd #48556)

Horizontal sum of the vector elements.

The intrinsic performs a tree-reduction of the vector elements. That is, for an 8 element vector:

((x0 + x1) + (x2 + x3)) + ((x4 + x5) + (x6 + x7))

Integer vectors

If an operation overflows it returns the mathematical result modulo 2^n where n is the number of times it overflows.

Floating-point vectors

If one of the vector element is NaN the reduction returns NaN.
