(2) has a unclear description. The standard document says:
constexpr bitset(unsigned long long val) noexcept; Effects: Constructs an object of class bitset<N>, initializing the first M bit positions to the corresponding bit values in val. M is the smaller of N and the number of bits in the value representation (3.9) of unsigned long long. If M < N, the remaining bit positions are initialized to zero.

 Exceptions for (3) and (4)
The page lists only std::out_of_range for (3), but as it notes above, it can also throw std::invalid_argument. Also, I think (4) should have the same exceptions as (3). I'd propose adding these to the "Exceptions" (out_of_range and invalid_argument for both (3) and (4)). Mortenpi (talk) 09:42, 21 May 2014 (PDT)
