 At the repl, 4d-324 throws a reader error.  But the nearest float to
 4d-324 is {{{least-positive-double-float}}} so we should probably return
 that instead of throwing an error.

 But values less than {{{0.5 * least-positive-double-float}}} could be
 rounded to 0, but I think the reader error is still appropriate.  CLHS
 2.3.1.1 says exponents that are out of range should signal a reader error.
