       class std::subtract_with_carry_engine< _UIntType, __w, __s, __r >"The Marsaglia-Zaman generator.

       This is a model of a Generalized Fibonacci discrete random number generator, sometimes referred to as the
       SWC generator.

       A discrete random number generator that produces pseuoorandom numbers using:
           x_{i}tarrow(x_{i - s} - x_{i - r} - carry_{i-1}) d ]

       The size of the state is $r$ and the maximum period of the generator is $(m^r - m^s - 1)$.

       Inserts the current state of a % subtract_with_carry_engine random number generator engine __x into the
       output stream __os.

       Parameters__os An output stream.
           __x A % subtract_with_carry_engine random number generator engine.

       Returns
           The output stream with the state of __x inserted or in an error state.

       Compares two % subtract_with_carry_engine random number generator objects of the same type for equality.

       Parameters__lhs A % subtract_with_carry_engine random number generator object.
           __rhs Another % subtract_with_carry_engine random number generator object.

       Returns
           true if the infinite sequences of generated values would be equal, false otherwise.

       Extracts the current state of a % subtract_with_carry_engine random number generator engine __x from the
       input stream __is.

       Parameters__is An input stream.
           __x A % subtract_with_carry_engine random number generator engine.

       Seeds the initial state $x_0$ of the % subtract_with_carry_engine random number generator.

   template<typename_UIntType,size_t__w,size_t__s,size_t__r>voidstd::subtract_with_carry_engine<_UIntType,__w,__s,__r>::seed(result_type__sd=0u)
       Seeds the initial state $x_0$ of the random number generator. N1688[4.19] modifies this as follows. If
       __value == 0, sets value to 19780503. In any case, with a linear congruential generator lcg(i) having
       parameters $ m_{lcg} o 2147483563,oa_{lcg} = 40014, c_{lcg} = 0, and lcg(0) = value $, sets $ x_{-r} ots
       x_{-1} $ to $ lcg(1) d ots lcg(r) d $ respectively. If $ x_{-1} = 0 $ set carry to 1, otherwise sets
       carry to 0.
