std::experimental::simd::operator!,~,+,-(3)

NAME
std::experimental::simd::operator!,~,+,- - std::experimental::simd::operator!,~,+,-

Synopsis
   mask_type operator!() const noexcept; (1) (parallelism TS v2)
   simd operator~() const noexcept; (2) (parallelism TS v2)
   simd operator+() const noexcept; (3) (parallelism TS v2)
   simd operator-() const noexcept; (4) (parallelism TS v2)
   Applies the given unary operator on each element of the simd.
   1) Returns a simd_mask<T, Abi> where the i^th element equals !operator[](i) for all
   i in the range of [0, size()).
   2) Returns a simd where each bit is the inverse of the corresponding bit in *this.
   This overload participates in overload resolution only if T is an integral type.
   3) Returns a copy of itself.
   4) Returns a simd where the i^th element is initialized to -operator[](i) for all i
   in the range of [0, size()).

Example
// Run this code
 #include <cstddef>
 #include <experimental/simd>
 #include <iostream>
 #include <string_view>
 namespace stdx = std::experimental;
 void println(std::string_view op, const stdx::native_simd_mask<int> x)
 {
     std::cout << op << ": ";
     for (std::size_t i = 0; i < x.size(); ++i)
         std::cout << std::boolalpha << x[i] << ' ';
     std::cout << '\n';
 }
 void println(std::string_view op, const stdx::native_simd<int> x)
 {
     std::cout << op << ": ";
     for (std::size_t i = 0; i < x.size(); ++i)
         std::cout << x[i] << ' ';
     std::cout << '\n';
 }
 int main()
 {
     const stdx::native_simd<int> a([](int i) { return i; });
     println(" a", a);
     println(" !a", !a);
     println(" ~a", ~a);
     println("~~a", ~~a);
     println(" +a", +a);
     println(" -a", -a);
     println("+-a", +-a);
 }

Possible output:
   a: 0 1 2 3
  !a: true false false false
  ~a: -1 -2 -3 -4
 ~~a: 0 1 2 3
  +a: 0 1 2 3
  -a: 0 -1 -2 -3
 +-a: 0 -1 -2 -3
