-- This package provides some common utilities used by the s-imgxxx files
package System.Img_Util is
pragma Pure;
procedure Set_Decimal_Digits
(Digs : in out String;
NDigs : Natural;
S : out String;
P : in out Natural;
Scale : Integer;
Fore : Natural;
Aft : Natural;
Exp : Natural);
-- Sets the image of Digs (1 .. NDigs), which is a string of decimal digits
-- preceded by either a minus sign or a space, i.e. the integer image of
-- the value in units of delta of a decimal fixed point type with the given
-- Scale, starting at S (P + 1), updating P to point to the last character
-- stored, the caller promises that the buffer is large enough and no check
-- is made for this. Constraint_Error will not necessarily be raised if the
-- 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. Note that there is no
-- leading space stored. The call may destroy the value in Digs, which is
-- why Digs is in-out (this happens if rounding is required).
