RE: AriCalculator is a home made pocket calculator.
There are much better generators than linear congruential.

The xorshift+ generator is fast and reasonable, the xorshift* generator relies on a long multiplication, so it isn't as fast on many devices.

The WP 34S uses the Tausworthe generator from the GNU Scientific Library, very fast, very long period and maximally equidistributed. The paper by Pierre L’Ecuyer is enlightening and includes the derived generator on the second last page.
