re: DEC2FRAC by Joseph K. Horn, posted 21 March 1991.

At the March 22nd meeting of the Orange/Los Angeles Counties Chapter
of the HP-48 users club, Harry Bertucelli objected to my contention
that DEC2FRAC finds ALL possible fractions.

Harry is a professional mathematician, and accepts nothing without a
formal proof.  So he withdrew to a corner of the room and into a
deeper corner of his mind, and in short order developed a complete
proof that DEC2FRAC does in fact find all possible fractions (up to
the point where the HP 48 begins to introduce round-off errors, of
course).  It made his day to see (and prove the validity of) a
completely new algorithm in number theory.  It made my day to know
that the very first computer to run it was an HP 48SX.
