HP-17BII+ serial

[Elwin]

I did some tests with my silver 17BII+ and found something that allows you access all the numbers in the sequence while still iterating twice each time it runs.

RAN#=L(A:FP(9821xSEED+.211327))+0xL(SEED:G(A))

The first iteration is stored in RAN# and the second iteration is stored in SEED. Solving for RAN# a second time produces the third and fourth numbers in the sequence.

Nothing changes if you multiply the first L() by 0 instead of the second.

I haven't been able to figure out why it works this way.
