(That's `cl-random' these days.)

The Common Lisp version of `random' supports float and integer values
depending on what type its argument has.  I guess that's what
`cl-random' is based on.

I'm not sure if we can change `random' to do the same.  But if there is
a need for random floating point numbers, it does seem unfortunate that
we only have that functionality in CL-Lib.
