It's fast, small, and amazingly robust. I'm kind of amazed how much has been done in this area the last few years.

I looked at the algorithm. It produces a 64-bit integer. Even if presented as a 0.0 to 1.0 range, it has a granularity of 5e-20 (actually 2^-64). I wonder if it's enough for newRPL with a default precision of 32 digits? In other words, if it provides 18 random digits, what do we fill the other 14 with?
