| P : out Natural; |

| -- Computes fixed_type'Image (V), where V is the integer value (in units of |
| -- delta) of a decimal type whose Scale is as given and stores the result |
| -- S (1 .. P), updating P on return. The result is computed according to |
| -- the rules for image for fixed-point types (RM 4.10(14)). The caller |
| -- guarantees that S is long enough to hold the result and has a lower |
| -- bound of 1. |

| -- Sets the image of V, where V is the integer value (in units of delta) |
| -- of a decimal type with the specified Scale, starting at S (P + 1) and |
| -- updating P to point to the last character stored, the caller promises |
| -- that the buffer is large enough and no check is made. Constraint_Error |
| -- will not necessarily be raised if this requirement is violated, since |
| -- it is perfectly valid to compile this unit with checks off. The Fore, |
| -- Aft and Exp values can be set to any valid values for the case of use |
| -- by Text_IO.Decimal_IO. |
