◆ slice()

constexpr uint256_t numeric::uint256_t::slice ( uint64_t  start,
uint64_t  end 
) const
constexpr

Viewing this uint256_t as a bit string, and counting bits from 0, slices a substring.

Returns
the uint256_t equal to the substring of bits from (and including) the start-th bit, to (but excluding) the end-th bit of this.
