Note:
The
[¥#]
key
(and
[it]
[¥*])
key
sequences
perform
calculations
that
involve
quite
a
few
steps
inside
your
calculator,
and
it
takes
a
little
longer
to
complete
these
calculations
than
others.
Be
sure
you
wait
for
your
calculator
to
finish
—
with
a
final
result
in
the
display
before
pressing
additional
keys.
