Return bit size of internal state, i.e dimension of GF(2)-vector space.
It will be Mersenne Exponent, when generator use incomplete array, like Mersenne Twister.
- Returns
- bit size of internal state
Implemented in MTToolBox::MersenneTwister, MTToolBox::MersenneTwister64, and MTToolBox::Sequential< T >.

initialize internal state
Initialization function does not need to be a GF(2)-linear function, non-GF(2)-linear function will be suitable. But as far as MTToolBox concerned, initialization only need to assure that the internal state is not zero. When generator use incomplete array, like Mersenne Twister, really used part of array should be set non-zero.
- Parameters
-
[in] value seed of initialization
Implemented in MTToolBox::MersenneTwister64, MTToolBox::MersenneTwister, and MTToolBox::Sequential< T >.
Referenced by MTToolBox::TestLinearity< U, V >::operator()().
