It is the fault of mathematics, and not any particular one the groups you named.

Floating point numbers simply cannot be stored precisely on a computer. And the most efficient representations to use do not round off to nice-looking numbers in base 10. So what is probably happening is that Access is storing the floating point number as a float. Perl stores it as a double. And since Perl stores it with much more accuracy than it was stored in the database with, when you display it in Perl you can see the round-off error.

UPDATE
merlyn is of course right. There are a finite number of exceptions. How many and what they are depends on the particular hardware you have, and the particular physical representation of a floating point number that you choose to use.
