Selecting the Display Notation and Decimal Places

The calculator has four display notation systems for displaying calculation results. When FIX, SCI, or ENG symbol is displayed, the number of decimal places can be set to any value between 0 and 9. Displayed values will be reduced to the corresponding number of digits.

10000-3-

[Floating point]	ONC 100000 + 3 =	33333.33333
-[FIXed decimal point]	ONF PTR	33333.33333
[TAB set to 2]	ONF TAB 2	33333.33
-[SCientific notation]	ONF FISL	3.33-10'
-[ENGneering notation]	ONF FOR	33.33-10'
-[Floating point]	ONF FISL	33333.33333

- If the value for floating point system does not fit in the following range, the calculator will display the result using scientific notation system:

0.000000001 ≤ |t| ≤ 9999999999

Determination of the Angular Unit

In this calculator, the following three angular units can be speci-tied:

SCIENTIFIC CALCULATIONS

• Press 2nd MODE 0 to select the normal mode.

- In each example, press [wE] to clear the display. And if the FIX, SCI, or ENG indicator is displayed, clear the indicator by pressing [wF] [FSE].

Arithmetic Operations

- The closing parenthesis ☐ just before - or M. may be omitted.

Constant Calculations

• In the constant calculations, the addend becomes a constant. Subtraction and division are performed in the same manner. For multiplication, the multiplicand becomes a constant.

- When performing calculations using constants, constants will be displayed as K.

Functions (4)

• Refer to operation examples of each function. • Before starting calculation, specify the angua

- The results of inverse trigonometric functions are displayed within the following range:

	= ^-1x, = ^-1x	= ^-1x
DEG	- 60 ≤ 8 ≤ 90	0 ≤ 8 ≤ 180
RAD	- 2 ≤ 8 ≤ 2	0 ≤ 8 ≤ x
GRAD	- 100 ≤ 8 ≤ 100	0 ≤ 8 ≤ 200

Differential/Integral Functions

Differential and integral calculations are only available in the normal mode. For calculation conditions such as the x value in differential calculation or the initial point in integral calculation, only numerical values can be entered and equations such as 2^x cannot be specified. It is possible to reuse the same equation over and over again and to recalculate by only changing the conditions without re-entering the equation.

- When performing a calculation, the value stored in the X memory will be cleared.

- When performing a differential calculation, enter formula first and then enter x value in differential calculation and minute interval (dx). If a numerical value is not specified for minute interval, x > 0 will be x · 10^-4 and x > 0 will be 10^-3 from the value of the numeric derivative.

- When performing a integral calculation, enter formula first and then enter a range of integral [a, b] and subintervals (n) . If a 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 which contain discontinuous points.

Integral calculation (Simpson's rule):

S= 12h(f(a)+4(f(a+b)+f(a+2b)+·s+f(a+(N-1)b)))

+2[f(a + 2b) + f(a + 4b) + +f(a + (N - 2h)] + f(h)]

Differential calculation:

[When performing integral calculations] Integral calculations, depending on the integrands and subintervals included, require longer calculation time. During calculation, "Calculating!" will be displayed. To cancel calculation, press (CMC). In addition, please note that there will be greater integral errors when there are large fluctuations in the integral values during minute shifting of the integral range and for periodic functions, etc., where positive and negative integral 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 Numbers

A pseudo-random number with three significant digits can be generated by pressing [2× F] [1× w] . To generate the next random number, press ____. You can perform this function in the normal and statistics modes. (You cannot perform this function while you are using the N-Base function.)

- Random numbers use memory Y. Each random number is generated on the basis of the value stored in memory Y (pseudo-random number series).

Angular Unit Conversions (6) Each time 2 3 4 are pressed, the angular unit changes in sequence.

Memory Calculations

This calculator has 6 temporary memories (A-D, X and Y), one independent memory (MI) and one last answer memory (ANS).

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 entering multiple instructions.

Fraction Calculations

This calculator performs arithmetic operations and memory calculations using a fraction, and conversion between a decimal number and a fraction.

• In all cases, a total of up to 10 digits including integer, numerator, denominator and the symbol (Γ) can be entered.

- If the number of digits to be displayed is greater than 10, the number is converted to and displayed as a decimal number.

• A decimal number, variable, or exponent cannot be used in a fraction.

Binary, Octal, Decimal, and Hexadecimal Operations

(N-Base) (10) This calculator can perform conversions between numbers expressed in binary, octal, decimal and hexadecimal systems. It can also perform the four basic arithmetic operations, calculations with parentheses and memory calculations using binary, octal, decimal, and hexadecimal numbers. In addition, the calculator can carry out the logical operations AND, OR, NOT, NEG, XOR and XNOR on binary, octal and hexadecimal numbers.

Conversion to each system is performed by the following keys:

204 54. Converts to the binary system. 6 appears

(2) ☐ (3). Converts to the octal system. ☐ appears

(a) -ex: Converts to the hexadecimal system. h appears

Self-Doc: Converts to the decimal system. a, b, and R 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 [ua], [b", [c1], [log], [vi], and [DRC],

and displayed as follows:

A - R, B - b, C - ℓ, D - d, E - ℓ, F - ℓ

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 hexadecimal 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 truncated. In the binary, octal, and hexadecimal systems, negative numbers are displayed as a complement.

Time, Decimal and Sexagesimal Calculations (11)

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.

Coordinate Conversions

• Before performing a calculation, select the angular unit

• The calculation result is automatically stored in memories X and Y.

Modify Function (13) In this calculator, all calculation results are internally obtained in scientific notation with up to 12 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 converted to match that of the display, so that the displayed value can be used without change in subsequent operations.

COMPLEX NUMBER CALCULATIONS (14)

To carry out addition, subtraction, multiplication, and division using complex numbers, press 2ref 10000 1 to select the complex number mode.

There are two modes of expression of the results of complex number calculations.
