std::independent_bits_engine(3)  C++ Standard Libary  std::independent_bits_engine(3) 
NAME¶
std::independent_bits_engine  std::independent_bits_engine
Synopsis¶
Defined in header <random>
template<
class Engine,
std::size_t W, (since C++11)
class UIntType
> class independent_bits_engine;
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
the type of the generated random numbers. The effect is undefined
UIntType  unless the parameter is cvunqualified and is one of unsigned
short,
unsigned int, unsigned long, or unsigned long long.
Type requirements¶

Engine must meet the requirements of RandomNumberEngine.

W must be greater than zero, and no greater than
std::numeric_limits<UIntType>::digits.
Member types¶
Member type Definition
result_type (C++11) UIntType
Member functions¶
constructor constructs the engine adaptor
(C++11) (public member function)
seed sets the state of the underlying engine
(C++11) (public member function)
base returns the underlying engine
(C++11) (public member function)
Generation¶
operator() advances the state of the underlying engine and
returns the
(C++11) generated value
(public member function)
discard advances the adaptor's state by a specified amount
(C++11) (public member function)
Characteristics¶
min gets the smallest possible value in the output range (always
zero).
[static] (C++11) (public static member function)
max gets the largest possible value in the output range (always 2w
[static] (C++11)  1).
(public static member function)
Nonmember functions¶
operator== compares the internal states of the adaptors and
operator!= underlying engines
(C++11) (function)
(C++11)(removed in C++20)
operator<< performs stream input and output on pseudorandom number
operator>> engine adaptor
(C++11) (function)
