Hi,

   with Ada.Text_IO; use Ada.Text_IO;
   procedure Floats is
      F : Float;
   begin

      --  from string ..
      F := Float'Value ("0.12345");

      --  to string, portably ...
      Put_Line ("F is " & Float'Image (F));

      --  to string, GNAT-only
      Put_Line ("F is " & F'Img);

   end Floats;

here, gives
  
   smaug.pushface.org[2]$ gnatmake floats
   gcc -c floats.adb
   gnatbind -x floats.ali
   gnatlink floats.ali
   smaug.pushface.org[3]$ ./floats
   F is  1.23450E-01
   F is  1.23450E-01
