5 / 5
For negative values, press [ +/– ] after entering the value; You can
enter a number in mantissa and exponent form by [ EXP ] key.

Parentheses calculations
Operations inside parentheses are always executed first. SR-281 /
SR-282 can use up to 13 levels of consecutive parentheses in a single
calculation.
Closed parentheses occurring immediately before operation of the [ ) ]
key may be omitted, no matter how many are required.

(Note) : A multiplication sign " x " occurring immediately before an
open parenthesis can be omitted.
The correct result cannot be derived by entering [ ( ] 2 [ + ] 3 [ ) ] [ EXP ]
2. Be sure to enter [ x ] between the [ ) ] and [ EXP ] in the below
example.

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.

Display notations
The calculator has the following display notations for the display
value.
Fixed-point / Floating Notations
To specify the number of decimal places, press [ 2nd ] [ TAB ] and then
a value indicating the number of places ( 0~9 ). Values are displayed
rounded off to the place specified. To return floating setting, press
[ 2nd ] [ TAB ] [ • ].
Scientific Notation
To change the display mode between floating and scientific notation,
press [ F
↔
E ].
Engineering Notation
Pressing [ ENG ] or [ 2nd ] [ ] will cause the exponent display for
the number being displayed to change in multiples of 3.
