The conversion between strings and float and strings and integers can
easily be accomplished using Ada.Text_IO.   Note that for 

         Ada.Text_IO.Integer_IO
   and   Ada.Text_IO.Float_IO

there are Get and Put operations defined for conversion between strings
and the desired numeric type.  Not only is this easy, it is also more
portable than some alternatives.   For some odd reason, this feature of
Ada.Text_IO is frequently undiscovered, even by programmers who have 
been using Ada for many years.
