enum class endian: signed int { little = 0, big = 1, native = little }: Endianness.

template <class To, class From> bit_cast(From const& src) noexcept: Casts value from one type to another by bit copy.
template <typename T, typename = std::enable_if_t<std::is_unsigned_v<T>>> auto bit_ceil(T x) → T constexpr noexcept: Returns the next power of two of the value.
template <typename T, typename = std::enable_if_t<is_num_v<T>>> auto byteswap(T x) → T constexpr noexcept: Reverses the byte order of the value.
template <typename T> auto byteswap_unchecked(T u) → T noexcept: Reverses the byte order of the value without checking for unique object representations.
template <typename T, typename = std::enable_if_t<std::is_integral_v<T>>> auto has_single_bit(T x) → bool constexpr noexcept: Checks if the value is an integral power of two.
template <typename T, typename = std::enable_if_t<std::is_integral_v<T>>> auto is_pow2(T x) → bool constexpr noexcept: Checks if the value is an integral power of two.
template <typename T, typename = std::enable_if_t<std::is_integral_v<T>>> auto popcount(T x) → int constexpr noexcept: Returns the number of 1 bits in the value.
template <typename T, typename = std::enable_if_t<is_num_v<T>>> auto to_big_endian(T x) → T constexpr noexcept: Reverses the byte order of the value if the native endianness is little.
template <typename T, typename = std::enable_if_t<is_num_v<T>>> auto to_little_endian(T x) → T constexpr noexcept: Reverses the byte order of the value if the native endianness is big.
