Thanks for the example.  A few remarks:

  (1) the float format in new Boot is double-float, so you don't need to
      say anything special to read double-float
  (2) new Boot uses the Lisp read to read constants, so reading the 
      Lisp formatted float should be straightforward to get in.  I'll look
      into that.
  (3) you can declare variable typs in Boot by specifying their types:
         var : type
