Hp Algorithm to create random numbers

[Gil]

With the first reference
I press, on my HP50G, the command RAND
and get R(n) =.821118792263 (1)
and build R(n)_int =821118792263 (an integer) (2)

Then I multiply 2851130928467 (3)
by R(n) and get 2.34111718457E12 (4)

Then I multiply also 2851130928467 (3)
by R(n)_int and get 2341117184566508886050821 (5)

Pressing a second time RAND gives
R(n+1)=.994325264552 (6)

I thought, with the explanations of the first reference,
that the digits of (6), R(n+1), should be found somewhere in (5) or (6).

But it's clearly not the case.

Could somebody explain my error or give a detailed example?

Thanks in advance.
