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(C++11) | std::subtract_with_carry_engine<std::uint_fast32_t, 24, 10, 24>
|
ranlux48_base(C++11) | 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 |
|
| constructs the engine (public member function) |
|
| sets the current state of the engine (public member function) |
|
Generation |
|
| advances the engine's state and returns the generated value (public member function) |
|
| advances the engine's state by a specified amount (public member function) |
|
Characteristics |
|
|
[static] | gets the smallest possible value in the output range (public static member function) |
|
[static] | gets the largest possible value in the output range (public static member function) |
Non-member functions
| compares the internal states of two pseudo-random number engines (function template) |
|
| performs stream input and output on pseudo-random number engine (function template) |
