Just to point out that 1/998 is not irrational.  It has a finite decimal
representation.  See:

http://en.wikipedia.org/wiki/Repeating_decimal

We can can compute the repeating decimal representation of a fraction by
repeated division on the remainders, and since there are only a finite
number of distinct remainders of 998, we're guaranteed to terminate at some
point, or find a loop.
