Floating point PRNG

I can't find any claim that it's better than xoroshiro128+, only xorshift or xoroshiro64.. from some other links:

I'll stick to it for now anyway either way.

For Crypto RNG, rdrand.. yep.. but it's slow as heck

Slow but unpredictable.
Not everybody wants fast food, sometimes it is better to wait a couple of nanoseconds more to eat something based on entropy.

Indeed, for the right application it's ideal.. I was planning on using it as a source of entropy/randomness to work on my telekinesis skills.. :) with a nice gui to boot.. haha

Google for "O'Neill" "Vigna" to see an interesting controversy.

P.S., your link to null program:

August 2018 Update: xoroshiro128+ fails PractRand very badly.

http://www.pcg-random.org/posts/a-quick-look-at-xoshiro256.html is also a good read 8)

Ahh good spot and some interesting reading.
I'll give the 256** version a go and see how it fares.
