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.

Contents

[edit] 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 effect is undefined unless the parameter is cv-unqualified 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.
