# `fast_random`

Portable random number generator predicates. Core predicates originally written by Richard O’Keefe. Based on algorithm AS 183 from Applied Statistics.

Remarks:

> - Single random number generator: This object provides a faster version of the `random` library object but does not support being extended to define multiple random number generators.

> - Randomness: Loading this object always initializes the random generator seed to the same value, thus providing a pseudo random number generator. The `randomize/1` predicate can be used to initialize the seed with a random value.
