🔗
template<class U, class A> constexpr explicit(sizeof(U) != Bytes) operator basic_vec<U, A>() const noexcept;
1
#
Constraints: simd-size-v<U, A> == simd-size-v<T, Abi>.
2
#
Returns: A data-parallel object where the element is initialized to static_cast<U>(operator[](i)).
🔗
constexpr bitset<size()> to_bitset() const noexcept;
3
#
Returns: A bitset<size()> object where the element is initialized to operator[](i) for all i in the range [0, size()).
🔗
constexpr unsigned long long to_ullong() const;
4
#
Let N be the width of unsigned long long.
5
#
Preconditions:
  • (5.1)
    size() <= N is true, or
  • (5.2)
    for all i in the range [N, size()), operator[](i) returns false.
6
#
Returns: The integral value corresponding to the bits in *this.
7
#
Throws: Nothing.
