std::experimental::simd<T,Abi>::size

std::experimental::simd<T,Abi>::size - cppreference.com

From cppreference.com

`static constexpr size_t size() noexcept;`		(parallelism TS v2)

Returns the width (the number of values) of simd<T, Abi>.

Example

The actual output depends on target and compiler flags.

#include <experimental/simd>
#include <cstdint>
#include <iostream>
namespace stdx = std::experimental;

int main()
{
    stdx::native_simd<std::int32_t> a = 1;
    std::cout << a.size() << '\n';
    std::cout << reduce(a) << '\n';
}

Possible output:

	obtains the number of elements of a given element type and ABI tag (class template) [edit]
[static] (parallelism TS v2)	returns the width / number of elements (public static member function of `std::experimental::simd_mask<T,Abi>`) [edit]
