[erlang-questions] [ANN] Erlang UUID

[Kenji Rikitake]

FYI:
A crude implementation in pure Erlang is available at
https://github.com/jj1bdx/sfmt-erlang/blob/master/src/random_wh06.erl
For the 2006 Wichmann-Hill RNG which Richard mentioned below.

Indeed true. Providing enough bits for the mantissa digits is required.

Me too - so far all I see is for fixed-length integers.
