operator string_type() const; (1) string_type str() const; (2) Converts to an object of the underlying std::basic_string type. The first version is an implicit conversion, the second one is explicit. Parameters (none). Return value Returns the matched character sequence as an object of the underlying std::basic_string type. If the matched member is false then the empty string is returned. Complexity Linear in the length of the underlying character sequence. Example #

explicit subtract_with_carry_engine( result_type value = default_seed ); (1) (since C++11) template< class Sseq > explicit subtract_with_carry_engine( Sseq& s ); (2) (since C++11) subtract_with_carry_engine( const subtract_with_carry_engine& ); (3) (since C++11) (implicitly declared) Constructs the pseudo-random number engine. The overload (2) only participate in overload resolution if Sseq qualifies as a SeedSequence. In particular, it is excluded from the se

difference_type length() const; Parameters (none). Return value Returns the number of characters in the match, i.e. std::distance(first, second) if the match is valid, 0 otherwise. Complexity Constant.

constexpr sub_match(); Default constructs a std::sub_match. The matched member is set to false and the value of other members is undefined. This is the only publicly accessible and defined constructor. Parameters (none).

explicit student_t_distribution( RealType n = 1 ); (1) (since C++11) explicit student_t_distribution( const param_type& params ); (2) (since C++11) Constructs new distribution object. The first version uses n as the distribution parameter, the second version uses params as the distribution parameter. Parameters n - the n distribution parameter (degrees of freedom) params - the distribution parameter set

void seed( result_type value = default_seed ); (1) (since C++11) template< class Sseq > void seed( Sseq& seq ); (2) (since C++11) Reinitializes the internal state of the random-number engine using new seed value. Parameters value - seed value to use in the initialization of the internal state seq - seed sequence to use in the initialization of the internal state Exceptions (none). Complexity

static constexpr result_type min(); (since C++11) Returns the minimum value potentially generated by the random-number engine. This value is equal to 0u. Parameters (none). Return value The minimum potentially generated value. Complexity Constant. See also max [static] gets the largest possible value in the output range (public static member function)

Defined in header <random> template< class UIntType, size_t w, size_t s, size_t r > class subtract_with_carry_engine; (since C++11) subtract_with_carry_engine is a random number engine that uses subtract with carry algorithm. The following typedefs define the random number engine with two commonly used parameter sets: Defined in header <random> Type Definition ranlux24_base std::subtract_with_carry_engine<std::uint_fast32_t, 24, 10, 24>

static constexpr result_type max(); (since C++11) Returns the maximum value potentially generated by the random-number engine. This value is equal to 2w - 1, where w is word_size. Parameters (none). Return value The maximum potentially generated value. Complexity Constant. See also min [static] gets the smallest possible value in the output range (public static member function)

void discard( unsigned long long z ); (since C++11) Advances the internal state by z times. Equivalent to calling operator() z times and discarding the result. Parameters z - integer value specifying the number of times to advance the state by Return value (none). Complexity See also operator() advances the engine's state and returns the generated value (public member function)
