Every scalar type comes with predefined attributes to convert from
string to that type, and from that type to a string.

Convert_String_To_Int:
declare
  Image : constant String := "42";
  Value : constant Integer := Integer'Value (Image);
begin
  null;
end Convert_String_To_Int;

Convert_Int_To_String:
declare
  Value : constant Integer := 42;
  Image : constant String := Integer'Image (Value);
begin
  null;
end Convert_Int_To_String;


To convert between Float and String, use Float'Image and Float'Value.

To convert between any scalar type T and String, use T'Image and
T'Value.
