(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 type must be unsigned integral type.
Type requirements
-
Engine must meet the requirements of RandomNumberEngine.
-
W must be greater than zero, and no greater than std::numeric_limits<UIntType>::digits().
