linear_congruential_t%next

Module: rngff

L6a21

L6a21: verified

Derivatives / callbacks: not applicable

Combined linear congruential generator with explicit two-seed state. The real64 overload widens a real32 draw. The checked driver independently evaluates both modular recurrences in int64, verifies states and real32-rounded outputs for 1000 steps, and checks exact replay.
