Defined in header <random>
template<     class Engine,     std::size_t W,     class UIntType > class independent_bits_engine;		(since C++11)

independent_bits_engine is a random number engine adaptor that produces random numbers with different number of bits than that of the wrapped engine.

Template parameters

Engine	-	the type of the wrapped engine
W	-	the number of bits the generated numbers should have
UIntType	-	the type of the generated random numbers. The type must be unsigned integral type.
Type requirements
- Engine must meet the requirements of RandomNumberEngine.

Member types

Member type	Definition
result_type	UIntType

Member functions

(constructor)	constructs the engine adaptor (public member function)
seed	sets the state of the underlying engine (public member function)
base	returns the underlying engine (public member function)
Generation
operator()	advances the state of the underlying engine and returns the generated value (public member function)
discard	advances the adaptor's state by a specified amount (public member function)
Characteristics
min [static]	gets the smallest possible value in the output range (always zero). (public static member function)
max [static]	gets the largest possible value in the output range (always 2w -1). (public static member function)

Non-member functions

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