std::linear_congruential_engine(3)

NAME
std::linear_congruential_engine - std::linear_congruential_engine

Synopsis
   Defined in header <random>
   template<
   class UIntType,
   UIntType a, (since C++11)
   UIntType c,
   UIntType m
   > class linear_congruential_engine;
   linear_congruential_engine is a random number engine based on Linear congruential
   generator (LCG). A LCG has a state that consists of a single integer.
   The transition algorithm of the LCG function is \(\small{x_{i+1}\leftarrow(a x_i +
   c)\mod m}\)x
   i+1 ← (ax
   i+c) mod m.
   The following typedefs define the random number engine with two commonly used
   parameter sets:

   Type Definition
                       std::linear_congruential_engine<std::uint_fast32_t, 16807, 0,
                       2147483647>
   minstd_rand0(C++11)
                       Discovered in 1969 by Lewis, Goodman and Miller, adopted as
                       "Minimal standard" in 1988 by Park and Miller
                       std::linear_congruential_engine<std::uint_fast32_t, 48271, 0,
                       2147483647>
   minstd_rand(C++11)
                       Newer "Minimum standard", recommended by Park, Miller, and
                       Stockmeyer in 1993

Template parameters
              The result type generated by the generator. The effect is undefined if
   UIntType - this is not one of unsigned short, unsigned int, unsigned long, or
              unsigned long long.
   a - the multiplier term
   c - the increment term
   m - the modulus term

Member types
   Member type Definition
   result_type(C++11) The integral type generated by the engine. Results are undefined
                      if this is not an unsigned integral type.

Member functions

Construction and Seeding
   constructor constructs the engine
   (C++11) (public member function)
   seed sets the current state of the engine
   (C++11) (public member function)

Generation
   operator() advances the engine's state and returns the generated value
   (C++11) (public member function)
   discard advances the engine's state by a specified amount
   (C++11) (public member function)

Characteristics
   min gets the smallest possible value in the output range
   [static] (C++11) (public static member function)
   max gets the largest possible value in the output range
   [static] (C++11) (public static member function)

Non-member functions
   operator== compares the internal states of two pseudo-random number
   operator!= engines
   (C++11) (function)
   (C++11)(removed in C++20)
   operator<< performs stream input and output on pseudo-random number
   operator>> engine
   (C++11) (function template)

Member constants
   constexpr UIntType multiplier the multiplier term (a).
   [static] (C++11) (public static member constant)
   constexpr UIntType increment the increment term (c).
   [static] (C++11) (public static member constant)
   constexpr UIntType modulus the modulus term (m).
   [static] (C++11) (public static member constant)
   constexpr UIntType default_seed the default seed (1).
   [static] (C++11) (public static member constant)
