33 -- signed integer types up to Size Integer'Size, and also for conversion
34 -- operations required in Text_IO.Integer_IO for such types.

43 -- Computes Integer'Image (V) and stores the result in S (1 .. P)
44 -- setting the resulting value of P. The caller guarantees that S
45 -- is long enough to hold the result, and that S'First is 1.

51 -- Stores the image of V in S starting at S (P + 1), P is updated to point
52 -- to the last character stored. The value stored is identical to the value
53 -- of Integer'Image (V) except that no leading space is stored when V is
54 -- non-negative. The caller guarantees that S is long enough to hold the
55 -- result. S need not have a lower bound of 1.
