Prof William “Mr IEEE-754” Kahan’s foreword to the “Standard Apple Numerics
Manual” had this to say about some of those machines:
For instance, a very Important Bunch of Machines launched in 1964
were found to have two anomalies in their double-precision
arithmetic (though not in single): First, multiplying a number /Z/
by 1.0 would lop off /Z/'s last digit. Second, the difference
between two nearly equal numbers, whose digits mostly canceled,
could be computed wrong by a factor almost as big as 16 instead of
being computed exactly as is normal. The anomalies introduced a
kind of noise in the feedback loops by which some programs had
compensated for their own rounding errors, so those programs lost
their high accuracies. These anomalies were not "bugs"; they were
"features" designed into the arithmetic by designers who thought
nobody would care. Customers did care; the arithmetic was
redesigned and repairs were retrofitted in 1967.
Not all Capriciously Designed Computer arithmetics have been
repaired. One family of computers has enjoyed notoriety for two
decades by allowing programs to generate tiny "partially
underflowed" numbers. When one of these creatures turns up as the
value of /T/ in an otherwise innocuous statement like
if T = 0.0 then Q := 0.0 else Q := 702345.6 / (T + 0.00189 / T);
it causes the computer to stop execution and emit a message
alleging "Division by Zero". The machine's schizophrenic attitude
toward zero comes about because the test for T = 0.0 is carried
out by the adder, which examines at least 13 of /T/'s leading
digits, whereas the divider and multiplier examine only 12 to
recognize zero. Doing so saved less than a dollar's worth of
transistors and maybe a picosecond of time, but at the cost of
some disagreement about whether a very tiny number /T/ is zero or
not. Fortunately, the divider agrees with the multiplier about
whether /T/ is zero, so programmers could prevent spurious
divisions by zero by slightly altering the foregoing statement as
follows:
if 1.0 * T = 0.0 then Q := 0.0 else Q := 702345.6 / (T + 0.00189 / T);
Unfortunately, the Same Computer designer responsible for "partial
underflow" designed another machine that can generate "partially
underflowed" numbers /T/ for which this statement malfunctions. On
that machine, /Q/ would be computed unexceptionably except that
the product 1.0 * T causes the machine to stop and emit a message
alleging "Overflow". How should a programmer rewrite that
innocuous statement so that it will work correctly on both
machines? We should be thankful that such a task is not
encountered every day.
