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).
x
Norm1: < 10
x
Norm2: < 10
Engineering Notation
Pressing [ ENG ] or [ 2nd ] [
for the number being displayed to change in multiples of 3.

Answer Function

Answer function stores the most recently calculated result. It is
retained even after the power is turned off. Once a numeric value or
numeric expression is entered and [ M+ ], [ 2nd ] [ M– ], [ RCL ],
[ 2nd ] [ STO ] or [ = ] is pressed, the result is stored by this function.
See Example 15.
(Note) : Even if execution of a calculation results in an error,
however, Answer memory retains its current value.

Scientific Function Calculations

Use COMP ( [ MODE ] 1 ( COMP ) ) mode for scientific function
calculations.
