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 types

Member type	Definition
result_type	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 (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)

Non-member functions

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)

constexpr size_t long_lag [static]	(public static member constant)
