[Determination of the Angular Unit]

The following three angular units (degrees, radians, and grads) can

be specified.

• °DEG ( ) : Press ”00.

• RAD (rad) : Press ”01.

•GRAD (g) : Press ”02.

[Selecting the Display Notation and Decimal Places]

Four display notation systems are used to display calculation re-

sults: Floating point; Fixed decimal point; Scientific notation; and

Engineering notation.

• When the FIX, SCI, or ENG symbol is displayed, the number of decimal

places (TAB) can be set to any value between 0 and 9. Displayed

values will be reduced to the corresponding number of digits.

[Setting the Floating Point Numbers System in Scientific Notation]

Two settings are used to display a floating point number: NORM1

(default setting) and NORM2. A number is automatically displayed

in scientific notation outside a preset range:

• NORM1: 0.000000001 ≤ ≤ x 9999999999

• NORM2: 0.01 ≤ ≤ x 9999999999

SCIENTIFIC CALCULATIONS

• Press m0 to select the normal mode.

• In each example, press ª to clear the display. If the FIX, SCI,

or ENG indicator is displayed, clear the indicator by selecting

‘ ’NORM1 from the SET UP menu.

Arithmetic Operations

• The closing parenthesis ) = ; just before or may be

omitted.

Constant Calculations

• In constant calculations, the addend becomes a constant. Sub-

traction and division are performed in the same manner. For

multiplication, the multiplicand becomes a constant.

• In the constants calculations, constants will be displayed as K.

Functions

• Refer to the calculation examples of each function.

• Before starting calculations, specify the angular unit.

Differential/Integral Functions

Differential and integral calculations are only available in the nor-

mal mode. For calculation conditions such as the value in differ-x

ential calculation or the initial point in integral calculation, only

numerical values can be entered and equations such as 22 cannot

be specified. It is possible to reuse the same equation over and

over again and to recalculate by only changing the conditions with-

out re-entering the equation.

• Performing a calculation will clear the value in the X memory.

•

When performing a differential calculation, enter the formula first and

then enter the x value in differential calculation and the minute interval

(dx). If a numerical value is not specified for minute interval,

≠0 will be



×10

–5

and

=0 will be 10

–5

from the value of the numeric derivative.

• When performing an integral calculation, enter the formula first

and then enter a range of integral ( ) and subintervals (n). If aa, b

numerical value is not specified for subintervals, calculation will

be performed using n=100.

Since differential and integral calculations are performed based on

the following equations, correct results may not be obtained, in

certain rare cases, when performing special calculations that con-

tain discontinuous points.

[When performing integral calculations]

Integral calculations, depending on the

integrands and subintervals included, require

longer calculation time. During calculation, “Cal-

culating!” will be displayed. To cancel calcula-

tion, press ª. Note that there will be greater

integral errors when there are large fluctua-

tions in the integral values during minute shift-

ing of the integral range and for periodic func-

tions, etc., where positive and negative inte-

gral values exist depending on the interval.

For the former case, divide integral intervals

as small as possible. For the latter case,

separate the positive and negative values.

Following these tips will allow results of calculations with greater

accuracy and will also shorten the calculation time.

Random Function

The Random function has four settings for use in the normal or

statistics mode. (This function cannot be selected while using the

N-Base function.) To generate further random numbers in succes-

sion, press . Press to exit.® ª

• The generated pseudo-random number series is stored in memory

Y. Each random number is based on a number series.

[Random Numbers]

A pseudo-random number, with three significant digits from 0 up to

0.999, can be generated by pressing @`0®.

[Random Dice]

To simulate a die-rolling, a random integer between 1 and 6 can be

generated by pressing @`1®.

[Random Coin]

To simulate a coin flip, 0 (head) or 1 (tail) can be randomly gener-

ated by pressing @`2®.

[Random Integer]

An integer between 0 and 99 can be generated randomly by press-

ing @`3®.

[Independent memory (M)]

In addition to all the features of temporary memories, a value can

be added to or subtracted from an existing memory value.

Press ªOM to clear the independent memory (M).

[Last answer memory (ANS)]

The calculation result obtained by pressing = or any other

calculation ending instruction is automatically stored in the last

answer memory.

[Formula memories (F1-F4)]

Formulas up to 256 characters in total can be stored in F1 - F4.

(Functions such as sin, etc., will be counted as one letter.) Storing

a new equation in each memory will automatically replace the

existing equation.

Note:

• Calculation results from the functions indicated below are auto-

matically stored in memories X or Y replacing existing values.

•Random function ...... Y memory

•→ θ → θr, xy ....................X memory (r x or ), Y memory ( or y)

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

up to 14 digits.

Chain Calculations

• The previous calculation result can be used in the subsequent

calculation. However, it cannot be recalled after entering multiple

instructions.

• When using postfix functions (¿ , sin, etc.), a chain calculation is

possible even if the previous calculation result is cleared by the

use of the keys.ª or @c

Fraction Calculations

Arithmetic operations and memory calculations can be performed

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)

Conversions can be performed between N-base numbers. The

four basic arithmetic operations, calculations with parentheses

and memory calculations can also be performed, along with 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 (“ ” “ ” appears.), @û ( appears.), @î

(“ ” appears.), @ì (“ ” appears.), @í (“ ” “ ”, ,

“ ” “ ” and disappear.)

Note: The hexadecimal numbers A – F are entered by pressing

ß ™ L, , , ÷, l I, 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 num-

bers are displayed as a complement.

Time, Decimal and Sexagesimal Calculations

Conversion between decimal and sexagesimal numbers can be

performed, and, while using sexagesimal numbers, conversion to

seconds and minutes notation. The four basic arithmetic opera-

tions and memory calculations can be performed using the

sexagesimal system. Notation for sexagesimal is as follows:

Coordinate Conversions

• Before performing a calculation, select the angular unit.

• The calculation result is automatically stored in memories X

and Y.

• •Value of r x or : X memory Value of θ or y: Y memory

Calculations Using Physical Constants

See the quick reference card and the English manual reverse side.

A constant is recalled by pressing followed by the numberß

of the physical constant designated by a 2-digit number.

The recalled constant appears in the display mode selected with

the designated number of decimal places.

Physical constants can be recalled in the normal mode (when not

set to binary, pental, octal, or hexadecimal), equation mode, or

statistics mode.

Note: Physical constants and metric conversions are based either

on the 2002 CODATA recommended values or 1995 Edi-

tion of the Guide for the Use of the International System of“

Units (SI)” released by NIST (National Institute of Stand-

ards and Technology) or on ISO specifications.
