What are your thoughts on the XORSHIFT+ PRNG that John brought up earlier? Does this have a long enough cycle for a practical use on calculator-based apps?

I have no data to back this up, but I'd be willing to bet that the "RAND n * CEIL" approach is used far more frequently than any other in calculator programs. Has this actually caused problems for anyone? I suspect we'll never really know.
