When
the
Cat calculates
it
maintains intermediate
values
(results
ofparts
of
a
longercalculation)
with l0
digits
to
the
right of
the
decimal
point.
This
minimizes rounding
errors
in
chained calculations.
Such
errors may occur when
an
intermediate result is
a
very small number
which
is
then
multiplied
by
a
large number.
For example, to calculate
the
daily
interest on
a
note,
you
divide
the interest rate
by
365 days and
multiply
by
the
principal. The intermediate result
-
interesV365
-
is
a
very
small
number.
If
the
calculation wasn't
carried out
to
a
precision
greater
than
four digits,
the
final
answer
could
be less
accurate due to the
rounding
offof
the
intermediate
result.
Numbers Too Large to Calculate
If
a
calculation
results
in
a
number that is too large
for
the
Cat to
display within
its
limitation of
l2
digits
to the
left
of
the
decimal point,
the
screen
displays >???.
??
If
you
use a
number that
exceeds
the
Cat's
limits
of
12
digits
to the
left
or
10
digits
to the
right
of
the
decimal
point
in
a
calculation,
the Cat beeps
and
[EXPLAIN]
describes the
limits.
Numbers
that
are
too small
become zero.
Number Punctuation
The
decimal
and
number style
line
on
the
Machine
Setup
screen
of
[SETUP]
can be used
to
select
various
types
of
number punctuation.
If
you
select 1,000,000.00,
for
ex-
ample,
your
results
will
be
displayed
with
commas
every
third digit
to
the
left
of
the
decimal
point. Typing
a
comma
any place
in
a
result
will
turn
on
this notation.
Further
use
of
[CALC]
will
display
that
particular
result
with
commas.
Other
types
of
punctuation are
offered
by
[SETUP].
In
Europe, commas mean decimal
points,
and
periods
occur
every
third
digil
1.000.000,00.
You
may also
select
Swiss
notation:
1'000'000.00.
You
should
be
careful when changing number
punctua-
tion.
For
example,
1.000
might
mean
"l"
when
you wrote
it,
but
could
mean
"
l
,000"
after
changing number punctua-
tion
with
[SETUP].
Calculation
results
and
relative
address
references
use
your
most
recently
selected number
punc-
tuation.
Changes
in
punctuation
won't affect
non-result
numbers, but
will
affect
results
producedby
sum,
averqge,
or relative
address
references.
