Applies the given unary operator on each element of the simd.
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 ith element is initialized to -operator[](i) for all i in the range of [0, size()).
Example
#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
