Answer that the
I Ching calculator purchased by
Dirk Gently in
Douglas Adams'
The Long Dark Teatime of the Soul gives for any math problem yielding a number greater than 4 (in addition to
hexagrams and
commentary on them). "Dirk was not certain if this was a programming error or an
insight beyond his ability to fathom, but he was crazy about it anyway, enough to hand over £20 of ready
cash for the thing."
Apparently at least one Javascript programmer has made a Web version of this calculator, now at http://www.thateden.co.uk/dirk/
