-------------------------+--------------------------------------------------
(read a)::Float fails if a is a string that is all digits but ends int "."

  (read "20.")::Float fails

  but

  (read "20.3"):: Float succeeds


   compare to the c atof function which succeeds in producing a correct
 value
   in both cases
