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.
