    • A system and method of generating uniform and independent random numbers is given by comprising two distinct odd primes that give an odd integer and an even integer, together with by taking an integer exponent and an integer exponent, by forming the composite modulus by taking a primitive root modulo and a primitive modulo and giving the multiplier modulo by either the system of congruence relations, any of which determines the multiplier modulo uniquely, by taking an initial value coprime. The method generates the sequence of integers by recursive congruence relations and gives an output of uniform and independent random numbers.

    • An invention is presented with new and simple ways of spectral tests applicable to the multiplicative congruential generator (d,z) with any odd modulus d and any multiplier z coprime to d. The invention realizes powerful ways to select multipliers of excellence with greatly improved statistical performances in their generation of uniform and independent random numbers. Related two inventions for new designs of the generator (d,z) are presented at the same time, as strongly facilitative for the application of advocated extended spectral tests, by exploiting specific structures of moduluses formed by two odd-prime-powers so as to realize improved periodic structures that are set conveniently out of tune avoiding harmful resonances.
