std::subtract_with_carry_engine

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>
`ranlux48_base`	std::subtract_with_carry_engine<std::uint_fast64_t, 48, 5, 12>

Member type	Definition
`result_type`	The integral type generated by the engine. Results are undefined if this is not an unsigned integral type.

Construction and Seeding
(constructor)	constructs the engine (public member function)
seed	sets the current state of the engine (public member function)
Generation
operator()	advances the engine's state and returns the generated value (public member function)
discard	advances the engine's state by a specified amount (public member function)
Characteristics
min [static]	gets the smallest possible value in the output range (public static member function)
max [static]	gets the largest possible value in the output range (public static member function)

operator==operator!=	compares the internal states of two pseudo-random number engines (function template)
operator<<operator>>	performs stream input and output on pseudo-random number engine (function template)
