Operational Notes
• Do not carry the calculator around in your back pocket, as
it may break when you sit down. The display is made of
glass and is particularly fragile.

Determination of the Angular Unit
In this calculator, the following three angular units (degrees,
radians, and grads) can be specified.
Press G
(rad)
Selecting the Display Notation and Decimal Places
•When calculation result is displayed in the floating point
system, pressing displays the result in the scientific∞
notation system.
Pressing ∞ once more displays the result again in the
floating point system.
•Pressing @i and any value between 0 and 9 speci-
fies the number of decimal places in the calculation result.
To clear the setting of decimal places, press @ i
..
SCIENTIFIC CALCULATIONS
•Calculate in the normal mode.
•In each example, press ª to clear the display.
Arithmetic Operations
•The closing parenthesis ) = ; just before or
may be omitted.
•When entering only a decimal place, it is not necessary to
press 0 before ..
Random Numbers
A pseudo-random number with three significant digits can be
generated by pressing @ ` . Random number gen-
eration is not possible when binary/octal/hexadecimal sys-
tem mode is set.
Angular Unit Conversions
Each time are pressed, the angular unit changes@ g
in sequence.
Memory Calculations
This calculator has one independent memory (M). It is avail-
able in the normal mode and binary, octal, hexadecimal
system mode.
•The independent memory is indicated by the three keys:
O R ;, , .
Before starting a calculation, clear the memory by press-
ing ª and O.
•A value can be added to or subtracted from an existing
memory value. When subtracting a number from the
memory, press ± and ;.
•The contents of the memory are retained even when the
calculator is turned off. A value stored in memory will thus
remain until it is changed or until the batteries run out.
Chain Calculations
This calculator allows the previous calculation result to be
used in the following calculation.
The previous calculation result will not be recalled after en-
tering multiple instructions.
Time, Decimal and Sexagesimal Calculations
This calculator performs decimal-to-sexagesimal conversion
and sexagesimal-to-decimal conversion. In addition, the four
basic arithmetic operations and memory calculations can be
carried out using the sexagesimal system.
Notation for sexagesimal is as follows:
123.404080
degree second
minute
Note: When the calculation or conversion result is con-
verted, a residual may occur.
Constant Calculations
•In the constant calculations, the addend becomes a con-
stant. Subtraction and division are performed in the same
manner. For multiplication, the multiplicand becomes a
constant.
Functions
•Refer to the calculation examples of each function.
•For most calculations using functions, enter numerical
values before pressing the function key.
STATISTICAL CALCULATIONS
Press @ Æ to select statistics mode.
The following statistics can be obtained:
x xMean of samples ( data)
sx Sample standard deviation (x data)
σ
x xPopulation standard deviation ( data)
nNumber of samples
Σ
x xSum of samples ( data)
Σ
x2Sum of squares of samples (x data)
Data Entry and Correction
Entered data are kept in memory until or @ Æ F
are pressed. Before entering new data, clear the memory
contents.

data)
[Data Correction]
Correction prior to pressing k:
Delete incorrect data with ª.
Correction after pressing k:
Reenter the data to be corrected and press @ J .
•The number displayed after pressing k @ J or
during data entry or correction is the number of samples
(n).
Statistical Calculation Formulas
In the statistical calculation formulas, an error will occur when:
•the absolute value of the intermediate result or calculation
result is equal to or greater than 1 × 10
100.
•the denominator is zero.
•an attempt is made to take the square root of a negative
number.
BINARY, OCTAL, DECIMAL, AND
HEXADECIMAL OPERATIONS (N-BASE)
This calculator can perform the four basic arithmetic opera-
tions, calculations with parentheses and memory calcula-
tions using binary, octal, decimal, and hexadecimal num-
bers.
When performing calculations in each system, first set the
calculator in the desired mode before entering numbers.
It can also perform conversions between numbers expressed
in binary, octal, decimal and hexadecimal systems.
Conversion to each system is performed by the following
keys:
Ï ê : Converts to the binary system. “ ”BIN appears.
Ï î : Converts to the octal system. “ ”OCT appears.
Ï ì : Converts to the hexadecimal system. “ ”HEX
appears.
Ï í : Converts to the decimal system. “ ”BIN , “ ”OCT ,
and HEX“ ” disappear from the display.
Conversion is performed on the displayed value when these
keys are pressed.
Note: In this calculator, the hexadecimal numbers A – F are
entered by pressing E, , , , Ñ ⁄ ´ I,
and l, and displayed as follows:
A → å, B → ∫, C → ç, D → ∂, E → é, F → ƒ
In the binary, octal, and hexadecimal systems, fractional
parts cannot be entered. When a decimal number having a
fractional part is converted into a binary, octal, or hexadeci-
mal number, the fractional part will be truncated. Likewise,
when the result of a binary, octal, or hexadecimal calculation
includes a fractional part, the fractional part will be trun-
cated. In the binary, octal, and hexadecimal systems, nega-
tive numbers are displayed as a complement.

A B C D E
COMPLEX NUMBER CALCULATIONS
To carry out addition, subtraction, multiplication, and division
using complex numbers, press to select the com-@π
plex number mode.
•A complex number is represented in the a + bi format. The
“ ” “ ”a is the real part while the bi is the imaginary part.
When inputting the real part, after inputting the number
press a. When inputting the imaginary part, after in-
putting the number press . To obtain the result pressb
=.
•Immediately after completing calculation, you can recall
the value of the real part with , and the value of thea
imaginary part with b.
•If the complex numbers are represented as polar coordi-
nates, press after they are input with @} a
and b.
ERROR AND CALCULATION RANGES
Errors
An error will occur if an operation exceeds the calculation
ranges, or if a mathematically illegal operation is attempted.
In the case of an error, the display will show “ ”E .
An error can be cleared by pressing ª.
Calculation Ranges
•Within the ranges specified, this calculator is accurate to
±1 of the least significant digit of the mantissa. However, a
calculation error increases in continuous calculations due
to accumulation of each calculation error. (This is the
same for yx, x¿ ,
e
x,
ln
, etc., where continuous calculations
are performed internally.)
Additionally, a calculation error will accumulate and
become larger in the vicinity of inflection points and
singular points of functions.
•Calculation ranges
±10
-99 ~ ±9.999999999×1099 and 0.
If the absolute value of an entry or a final or intermediate
result of a calculation is less than 10–99, the value is consid-
ered to be 0 in calculations and in the display.
