If
you
want to count the number
of
tab characters
in
front
of
each
entry
in
your columns,
highlight
the
whole
table
and count the arrows that
represent
tab
characters.
All
column entries (including sum, sumdisplay, avg,
or
average)
must have
the
same
number
of
tab
characters
preceding
them.
You
can
perform
operations on
a
column with
the
follow-
ing column
operators:
Operator
Meaning
sum
Add
the values
in
the
column
above
avg
Average the values
in
the
column
above
(you
can also
use
the
word "average"
in
stead
of "avg")
sum
display
Add
the
displayed
values
in
the
column
above
Typing "sum"
or
"avg"
at the
bottom
of
a
column, high-
lighting
it,
and
using
[CALC]
calculates
the sum
or
average
respectively.
The
result
appears in
place of
the
highlighted
expression.
The operators may
be used
by themselves,
or
in
an
expression.
If
used
in
an
expression, the sum or
average
is
calculated
and the
result
is
used in
evaluating the
expression.
Sumdisplay is the
same
as
sum
except
that
it
uses
the
displayed,
rather than the
underlying
values.
Remember
that
underlying
values
are
carried
to
a
precision
of
l0
digits
to
the
right of
the
decimal
point, while
the
displayed value
is
rounded
to the
number
of
digits you
select
on
the
Decimal places
in
calculations line
of
the Machine
Setup
screen
of
[SETUP]
(see
Screen
2:
Machine
Setup,
pages
97-98,
for
more information).
The
following
example shows
two
numbers that produce
different
results, depending
on
whether you
add
them
with
sum
er
sumdisplay. The displayed
values
have
been
rounded
as
will
happen
if
you
erase
the
numbers
to
the
right
of
the
decimal point in
the results and use
[CALC]
again.
Displayed
value
Pocketed value
41.4
20.4
Using
[CALCf
on
sum
will
yield
62 (41.4
+
20.4
=
61.8
rounded
upward); Using
[CALC]
on sumdisplay
will
yield
6l
because
it
adds
the displayed values (41
+ 20).
The
example
was
done
with
the
Decimal
places
in
calcula-
tions
line
set
to
0
in
the
Machine
Setup
screen
of
[SETUP];
if
the
Decimal
places
in calculations
line
had
been
set
to
the
initial
value
of
2,
using
[CALC] on
sum
and
sumdisplay
would yield
62.00 and
61.00 respectively.
