It is _only_ when you write it to a screen or a string that the notion
of base 10 or base 16 matters. When an integer is stored in a
variable, such as 'a' above, it is represented as a particular pattern
of bits in RAM, normally base 2 binary.

Ada.Integer_Text_IO can write to a string as well as to the screen or
a file:

with Ada.Text_IO;
with Ada.Integer_Text_IO;
procedure Hex_Image is
   A : Integer := 10;
   Image_A : String (1 .. 10); -- bigger than needed, padded with spaces
begin
   Ada.Integer_Text_IO.Put (To => Image_A, Item => A, Base => 16);

   Ada.Text_IO.Put_Line ("The image we get is '" & Image_A & "'");
end Hex_Image;
