Results equal to or greater than 10
10
or results less than 10
–9
are
displayed in exponential form. See Example 9.
Parentheses calculations
Operations inside parentheses are always executed first. The
calculator Math mode can use up to 24 levels and Linear mode can
use up to 25 levels of consecutive parentheses in a single
calculation.
Closed parentheses occurring immediately after operation of the [ ) ]
key may be omitted, no matter how many are required. See Example
10.
(Note) : A multiplication sign " x " occurring immediately before
an open parenthesis can be omitted.
The correct result cannot be derived by entering [ ( ] 2 [ + ] 3 [ ) ]
[ x10
x
] 2. Be sure to enter [ x ] between the [ ) ] and [ x10
x
] in
Example 11.
Percentage calculation
[ 2nd ] [ % ] divides the number in the display by 100. You can use
this key sequence to calculate percentages, add-ons, discounts, and
percentage ratios. See Example 12~13.
Display notations
The calculator has the following display notations for the display
value. See Example 14.
Fixed Decimal Point Notation
To specify the number of decimal places, press [ 2nd ] [ SET UP ]
[ 6 ] and then a value indicating the number of places ( 0~9 ). Values
are displayed rounded off to the place specified.
Scientific Notation
Scientific notation expresses numbers with one digit to the left of the
decimal and the appropriate power of 10.
To select scientific notation, press [ 2nd ] [ SET UP ] [ 7 ], and then a
value (0~9) to specify the number of decimal digits. Values are
displayed rounded off to the place specified.
Norm Notation
Press [ 2nd ] [ SET UP ] [ 8 ] and then select Norm1 (the default) or
Norm2 to determine the range to display the result in
non-exponential format (within the range) or in exponential format
(out of the range).
Norm1:
x
<
10
-2
,

≧

Norm2:

Engineering Notation
Pressing [ ENG ] or [ 2nd ] [
e
ENG ] will cause the exponent display
for the number being displayed to change in multiples of 3.
