Classics/HP25
X = 08000000002000 (8.000000002)
HP65/HP67/HP22/HP27/HP25c/HP34c/HP19c
08000000000000 (8.00)
HP21
X=07999997770000 (7.99999777)

As already noted, the 25 and 25C should return the same result 8,000000002, as does the HP65. Probably all other pre-1976 calculators are off here. The HP67, 34C and 19/29C use 13-digit precision and thus correctly return a plain 8.

BTW I am surprised at the HP21 result. What's going on there?
