or y)

• Temporary memories and last answer memory are cleared

even when the same mode is reselected.

• Use of R or K will recall the value stored in memory

using up to 14 digits.

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 enter-

ing multiple instructions.

• In the case of utilizing postﬁ x functions (¿ , sin, etc.), you can

perform a chain calculation even when the previous calculation

result is cleared by the use of the ª key.

Fraction Calculations

This calculator performs arithmetic operations and memory

calculations using fractions, and conversion between a decimal

number and a fraction.

• If the number of digits to be displayed is greater than 10, the

number is converted to and displayed as a decimal number.

Binary, Pental, Octal, Decimal, and Hexadecimal

Operations (N-Base)

This calculator can perform conversions between numbers

expressed in binary, pental, octal, decimal and hexadecimal

systems. It can also perform the four basic arithmetic operations,

calculations with parentheses and memory calculations using

binary, pental, octal, decimal, and hexadecimal numbers. In ad-

dition, the calculator can carry out the logical operations AND,

OR, NOT, NEG, XOR and XNOR on binary, pental, octal and

hexadecimal numbers.

Conversion to each system is performed by the following keys:

@ê : Converts to the binary system. “ ” appears.

@û : Converts to the pental system. “ ” appears.

@î : Converts to the octal system. “ ” appears.

@ì : Converts to the hexadecimal system. “ ” appears.

@í : Converts to the decimal system. “ ”, “ ”, “ ”, and

“ ” 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 ™

A, ⁄

B, L

C, ÷

D, l

E, and

, and displayed as follows:

A →

ï, B → ∫, C → ó, D → ò

, E → ô, F → ö

In the binary, pental, octal, and hexadecimal systems, fractional

parts cannot be entered. When a decimal number having a frac-

tional part is converted into a binary, pental, octal, or hexadeci-

mal number, the fractional part will be truncated. Likewise, when

the result of a binary, pental, octal, or hexadecimal calculation

includes a fractional part, the fractional part will be truncated.

In the binary, pental, octal, and hexadecimal systems, negative

numbers are displayed as a complement.

Time, Decimal and Sexagesimal Calculations

Conversion between decimal and sexagesimal numbers can be

performed. In addition, the four basic arithmetic operations and

memory calculations can be carried out using the sexagesimal

system.

Notation for sexagesimal is as follows:

degree second

minute

Coordinate Conversions

• Before performing a calculation, select the angular unit.

↔

P ( ,xy )

P (r,

)

• The calculation result is automatically stored in memories X

and Y.

Value of r or x: X memory

Value of θ or y: Y memory

Modify Function

In this calculator, calculation results are internally obtained in

scientiﬁ c notation with up to 14 digits for the mantissa. However,

since calculation results are displayed in the form designated by

the display notation and the number of decimal places indicated,

the internal calculation result may differ from that shown in the

display. By using the modify function, the internal value is con-

verted to match that of the display, so that the displayed value

can be used without change in subsequent operations.

STATISTICAL CALCULATIONS

Statistical calculations are performed in the statistics mode.

Press m1 to select the statistics mode. This calculator

performs the seven statistical calculations indicated below. After

selecting the statistics mode, select the desired sub-mode by

pressing the number key corresponding to your choice.

When changing to the statistical sub-mode, press the corre-

sponding number key after performing the operation to select the

statistics mode (press m1).

The following statistics can be obtained for each statistical calcula-

tion (refer to the table below):

Single-variable statistical calculation

Statistics of Q

Linear regression calculation

Statistics of Q and W and, in addition, estimate of y for a given

x (estimate y´) and estimate of

x for a given y (estimate x´)

Exponential regression, Logarithmic regression,

Power regression, and Inverse regression calculation

Statistics of Q and W. In addition, estimate of y for a given x

and estimate of x for a given y

. (Since the calculator converts

each formula into a linear regression formula before actual cal-

culation takes place, it obtains all statistics, except coefﬁ cients

and b, from converted data rather than entered data.)

Quadratic regression calculation

Statistics of Q and W and coefﬁ cients a, b, c in the quadratic

regression formula (

y = a + bx + cx2). (For quadratic regression

calculations, no correlation coefﬁ cient (r) can be obtained.)

When there are two x´

values, press @≠.

When performing calculations using a, b and c

, only one numeric

value can be held.

• Use K and R to perform a STAT variable calculation.

Data Entry and Correction

Entered data are kept in memory until @c are pressed or

mode selection. Before entering new data, clear the memory con-

tents.

[Data Entry]

Single-variable data

Data k

Data & frequency k (To enter multiples of the same

data)

Two-variable data

Data x & Data y

Data x & Data y & frequency k (To enter multiples

of the same data x

and y.)

• Up to 100 data items can be entered. With the single-variable

data, a data item without frequency assignment is counted as

one data item, while an item assigned with frequency is stored

as a set of two data items. With the two-variable data, a set of

data items without frequency assignment is counted as two data

items, while a set of items assigned with frequency is stored as

a set of three data items.

[Data Correction]

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 × 10100.

• The denominator is zero.

• An attempt is made to take the square root of a negative number.

• No solution exists in the quadratic regression calculation.

ERROR AND CALCULATION RANGES

Errors

An error will occur if an operation exceeds the calculation ranges,

or if a mathematically illegal operation is attempted. When an error

occurs, pressing < (or >) automatically moves the cursor

back to the place in the equation where the error occurred. Edit the

equation or press ª

to clear the equation.

Error Codes and Error Types

Syntax error (Error 1):

• An attempt was made to perform an invalid operation.

Ex. 2 @{

Calculation error (Error 2):

• The absolute value of an intermediate or ﬁ nal calculation result

equals or exceeds 10

100 .

• An attempt was made to divide by 0 (or an intermediate calculation

resulted in zero).

• The calculation ranges were exceeded while performing calculations.

Depth error (Error 3):

• The available number of buffers was exceeded. (There are 10 buffers*

for numeric values and 24 buffers for calculation instructions).

*5 buffers in STAT mode.

• Data items exceeded 100 in the statistics mode.

Equation too long (Error 4):

• The equation exceeded its maximum input buffer (142 characters).

An equation must be shorter than 142 characters.

Calculation Ranges

• Within the ranges speciﬁ ed, this calculator is accurate to

±1 of the least signiﬁ cant 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¿ , , n! e x, ln, etc., where continuous calculations are

performed internally.)

Additionally, a calculation error will accumulate and become

larger in the vicinity of inﬂ ection points and singular points

of functions.

• Calculation ranges

±10

–99 ~ ±9.999999999×10

99 and 0.

If the absolute value of an entry or a ﬁ nal or intermediate result of

a calculation is less than 10

–99 , the value is considered to be 0 in

calculations and in the display.
