WG1 - Core

description

Student programs often want a small amount of randomness, not necessarily of very high quality.  Shall we provide a simple interface to a random variable in WG1 Scheme?

I suggest we provide two procedures:


  `(random-integer ''n''`)`::
    Accepts a non-negative integer argument `n` as the exclusive upper bound of the result.  The inclusive lower bound is 0.
  `(random-real)`::
    Provides a real number with exclusive upper bound 1.0 and exclusive lower bound 0.0.

In both cases, the results appear to be independent and uniformly distributed.  This is the smallest conceivable subset of SRFI 27.  See the design rationale for "why" explanations.
