NAME¶
std::linear_congruential_engine< _UIntType, __a, __c, __m > - A model of a linear congruential random number generator.
SYNOPSIS¶
Public Types¶
typedef _UIntType result_type
Public Member Functions¶
template<typename _Sseq , typename = typename
std::enable_if<!std::is_same<_Sseq,
linear_congruential_engine>::value> ::type>
linear_congruential_engine (_Sseq &__q)
Constructs a linear_congruential_engine random number generator engine seeded
from the seed sequence __q. linear_congruential_engine
(result_type __s=default_seed)
Constructs a linear_congruential_engine random number generator engine with
seed __s. The default seed value is 1. void discard (unsigned
long long __z)
Discard a sequence of random numbers. result_type operator() ()
Gets the next random number in the sequence. template<typename _Sseq >
std::enable_if< std::is_class< _Sseq >::value
>::type seed (_Sseq &__q)
Reseeds the linear_congruential_engine random number generator engine sequence
using values from the seed sequence __q. void seed
(result_type __s=default_seed)
Reseeds the linear_congruential_engine random number generator engine sequence
to the seed __s.
Static Public Member Functions¶
static constexpr result_type max ()
Gets the largest possible value in the output range. static constexpr
result_type min ()
Gets the smallest possible value in the output range.
Static Public Attributes¶
static constexpr result_type default_seed
static constexpr result_type increment

operator== (const linear_congruential_engine &__lhs, const
linear_congruential_engine &__rhs)
Compares two linear congruential random number generator objects of the same
type for equality. template<typename _UIntType1 , _UIntType1 __a1,
_UIntType1 __c1, _UIntType1 __m1, typename _CharT , typename _Traits >
std::basic_istream< _CharT, _Traits > &
operator>> (std::basic_istream< _CharT, _Traits >
&__is, std::linear_congruential_engine< _UIntType1, __a1,
__c1, __m1 > &__lcr)
Sets the state of the engine by reading its textual representation from
__is.
Detailed Description¶
template<typename _UIntType, _UIntType __a, _UIntType __c, _UIntType __m>¶
class std::linear_congruential_engine< _UIntType, __a, __c, __m >" A model of a linear congruential random number generator.
A random number generator that produces pseudorandom numbers via linear function: x_{i+1}
The template parameter _UIntType must be an unsigned integral type large enough to store values up to (__m-1). If the template parameter __m is 0, the modulus __m used is std::numeric_limits<_UIntType>::max() plus 1. Otherwise, the template parameters __a and __c must be less than __m.
The size of the state is $1$.
