Ran056 Class

Ran056: Knuth's lagged Fibonacci random generator with 3-decimation. Returns integer random numbers uniformly distributed within [0,2147483647]. The period is 2^55/3 > 1.2*10^16.

Remarks
C#
Copy
   - At least 32 bit long int is required, but works with any larger
word lengths
   - This is the same lagged Fibonacci generator as Ran055
       x(n) =  ( x(n-55) - x(n-24) ) mod 2^31
   - but a decimation strategy is applied to remove the known
     correlations. Only every 3rd number will be used:
