Selecting the display notation and decimal places
Two settings of Floating point (NORM1 and NORM2), Fixed decimal point
(FIX), Scientific notation (SCI), and Engineering notation (ENG).
• When @ J 1 0 (FIX) or @ J 1 2 (ENG) is
pressed, the number of decimal places (TAB) can be set to any value
between 0 and 9.
• When @ J 1 1 (SCI) is pressed, the number of
significant digits can be set to any value between 0 and 9. Entering 0
will set a 10-digit display.
Setting the floating point number system in scientific notation
NORM1 (the default) and NORM2. A number is automatically displayed in
scientific notation outside a preset range:
NORM1 (@ J 1 3): 0.000000001
NORM2 (@ J 1 4): 0.01
Selecting the editor and setting the answer display
This calculator has the following two editors in NORMAL mode:
WriteView and Line.
Set the display format for numerical calculation results in WriteView editor.
The WriteView editor
p
EXACT(a/b,r, ) @ J 2 0 0 (default)
APPROX.
@ J 2 0 1
The Line editor
@ J 2 1
Notes:
p
• When "EXACT(a/b,r, )" is set, results will appear in fraction format or
irrational number format (including
• When "APPROX." is set, results will be decimal display or fraction
display, and will be not shown in irrational number format (including
and r).
• Press U to change the calculation results to another format that can
be displayed.
Adjusting the display contrast
Press @ J 3, then + or & to adjust the contrast. Press
j to exit.
Insert and overwrite entry methods
Х
When using the Line editor, you can change the entry method from
О "INSERT" (the default) to "OVERWRITE".
After you switch to the overwrite method (by pressing @ J 4 1),
О
the triangular cursor will change to a rectangular one, and the number or
function underneath it will be overwritten as you make entries.
Х
Setting the recurring decimal
О
In NORMAL mode, calculation results can be shown in a recurring
О
decimal format.
Recurring decimal is OFF : @ J 5 0 (default)
О
Recurring decimal is ON : @ J 5 1
• In the WriteView editor, the recurring part is indicated by "
Line editor, the recurring part is indicated in parentheses.
• If over 10 digits, including the recurring part, the result cannot be
displayed in recurring decimal format.
Setting of the decimal point
You can show the decimal point in the calculation result as either a dot
or a comma.
DOT: J 6 0 (default)
COMMA: J 6 1
• During entry, the decimal point is only shown as a dot.
Name display function
You can save a username in this calculator. When you turn the power off,
the saved username is displayed momentarily.
Up to 32 characters may be saved, split over two lines.
Entering and editing the username:
1. Press @ J 7. The editing screen appears with a flashing
cursor.
2. Use u and d to scroll through the available characters.
3. Pressing l or r moves the cursor to the left or right.
To modify a character, use l or r to move the cursor to the
character, then select another character using u or d.
4. Repeat steps 2 and 3 above to continue entering characters.
5. Press = to save and quit.
Note: Press @ Z in the editing screen to clear all the
characters.
ENTERING, DISPLAYING, AND EDITING THE EQUATION
The WriteView Editor
Entry and display
In the WriteView editor, you can enter and display fractions or certain
functions as you would write them.
• The WriteView editor can be used in NORMAL mode.
Displaying calculation results (when EXACT is selected)
When possible, calculation results will be displayed using fractions, r,
p
and . When you press U, the display will cycle through the following
display styles:
p
• Mixed fractions (with or without
p
without ) decimal numbers
• Proper fractions (with or without
• Irrational numbers (square roots, fractions made using square roots)
decimal numbers
Notes:
• In the following cases, calculation results may be displayed using r:
• Arithmetic operations and memory calculations
• Trigonometric calculations
• In trigonometric calculations, when
entering values such as those in the
table to the right, results may be shown
using .
r
• Improper/proper fractions will be
converted to and displayed as decimal
numbers if the number of digits used in
their expression is greater than nine. In the case of mixed fractions, the
maximum number of displayable digits (including integers) is eight.
• If the number of digits in the denominator of a fractional result that uses
p
is greater than three, the result is converted to and displayed as a
decimal number.
