A model of a linear congruential random number generator.
A random number generator that produces pseudorandom numbers via linear function:
The template parameter _UIntType
must be an unsigned integral type large enough to store values up to (__m-1). If the template parameter __m
is 0, the modulus __m
used is std::numeric_limits<_UIntType>::max() plus 1. Otherwise, the template parameters __a
and __c
must be less than __m
.
The size of the state is .
auto std::linear_congruential_engine< _UIntType, __a, __c, __m >::seed | ( | _Sseq & | __q | ) | -> _If_seed_seq<_Sseq> |
Seeds the LCR engine with a value generated by __q
.
