A model of a linear congruential random number generator.Member Typedef Documentation¶
template<class _UIntType, _UIntType __a, _UIntType __c, _UIntType __m> typedef _UIntType std::linear_congruential< _UIntType, __a, __c, __m >:: result_type¶
The type of the generated random value. Definition at line 353 of file tr1_impl/random.Constructor & Destructor Documentation¶
template<class _UIntType, _UIntType __a, _UIntType __c, _UIntType __m> std::linear_congruential< _UIntType, __a, __c, __m >:: linear_congruential (unsigned long__x0 = 1) [inline], [explicit]¶
Constructs a linear_congruential random number generator engine with seed __s. The default seed value is 1. Parameters:__s The initial seed value.
template<class _UIntType, _UIntType __a, _UIntType __c, _UIntType __m> template<class _Gen > std::linear_congruential< _UIntType, __a, __c, __m >:: linear_congruential (_Gen &__g) [inline]¶
Constructs a linear_congruential random number generator engine seeded from the generator function __g. Parameters:__g The seed generator function.
Member Function Documentation¶
template<class _UIntType, _UIntType __a, _UIntType __c, _UIntType __m> result_type std::linear_congruential< _UIntType, __a, __c, __m >::max () const [inline]¶
Gets the largest possible value in the output range. Definition at line 416 of file tr1_impl/random.template<class _UIntType, _UIntType __a, _UIntType __c, _UIntType __m> result_type std::linear_congruential< _UIntType, __a, __c, __m >::min () const [inline]¶
Gets the smallest possible value in the output range. The minimum depends on the __c parameter: if it is zero, the minimum generated must be > 0, otherwise 0 is allowed.

Gets the next random number in the sequence. Gets the next generated value in sequence. Definition at line 130 of file random.tcc.template<class _UIntType , _UIntType __a, _UIntType __c, _UIntType __m> void std::linear_congruential< _UIntType, __a, __c, __m >::seed (unsigned long__x0 = 1)¶
Reseeds the linear_congruential random number generator engine sequence to the seed __s. Parameters:__s The new seed.
Seeds the LCR with integral value __x0, adjusted so that the ring identity is
never a member of the convergence set.

Compares two linear congruential random number generator objects of the same type for inequality. Parameters:__lhs A linear congruential random
number generator object.
__rhs Another linear congruential random number generator obj.
Returns:
true if the two objects are not equal, false
otherwise.

Writes the textual representation of the state x(i) of x to __os. Parameters:__os The output stream.
__lcr A % linear_congruential random number generator.
Returns:
__os.

Compares two linear congruential random number generator objects of the same type for equality. Parameters:__lhs A linear congruential random
number generator object.
__rhs Another linear congruential random number generator obj.
Returns:
true if the two objects are equal, false
otherwise.

Sets the state of the engine by reading its textual representation from __is. The textual representation must have been previously written using an output stream whose imbued locale and whose type's template specialization arguments _CharT and _Traits were the same as those of __is. Parameters:__is The input stream.
__lcr A % linear_congruential random number generator.
Returns:
__is.
