>             Project: Commons Math
>          Issue Type: Improvement
>            Reporter: Gilles
>            Assignee: Gilles
>              Labels: api, refactoring
>             Fix For: 4.0
> It is proposed to refactor the whole package in order to fix the various problems mentioned
in recent issues and discussions 
> concerning the random number generators.
> For background, please refer to the separate reports on the issue tracking system, and
on the "dev" ML.
> The main goals are:
> # Make it clear that implementations do not generate an arbitrary number of bits (at
the request of the user); but rather as fixed size chunks (i.e. 32 bits, a.k.a. Java "int"
> # Allow implementations that generate 64 bits chunks (a.k.a. Java "long" type).
> # Separate the generation of sequences (for all Java primitive types) that are uniformly
distributed (in the range of the corresponding type) from all further processing (e.g. required
to match other distributions).
