Priority Levels in Calculation This calculator performs operations according to the following priority: 1 Functions such as sin, x2, and % 2 yx, x¿y 3 ×, ÷ 4 +, - 5 =, M+ and other calculation ending instruction • Calculations which are given the same priority level are executed in sequence. • If parentheses are used, parenthesized calculations have precedence over any other calculations. • Parentheses can be continuously used up to 15 times un- less pending calculations exceed 4. INITIAL SET UP Mode Selection Normal mode: ª Used to perform arithmetic operations and function calculations. BIN, OCT, HEX, CPLX and STAT are not displayed. Binary, Octal, Decimal, or Hexadecimal system mode or @ì Complex number mode: @π Used to perform arithmetic operations with complex numbers. To clear this mode, press @π. Statistics mode: @Æ Used to perform statistical calculations. To clear this mode, press @Æ. When executing mode selection, statistical data will be cleared even when reselecting the same mode. • By pressing F or Automatic power off function, the mode is cleared and returned to the normal mode. 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 specifies the number of decimal places in the calculation result. To clear the setting of decimal places, press @ i .. 100000÷3= [Floating point] [TAB set to 2] →[Scientific notation] →[Floating point] ª100000/3= @i 2 ∞ ∞@i. 33333.33333 33333.33 3.33 04 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 ≤ | x | ≤ 9999999999 Determination of the Angular Unit In this calculator, the following three angular units (degrees, radians, and grads) can be specified. DEG (°) Press G GRAD (g) RAD (rad) 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 .. 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. Random Numbers A pseudo-random number with three significant digits can be generated by pressing @ `. Random number generation is not possible when binary/octal/hexadecimal system mode is set. Angular Unit Conversions Each time @ g are pressed, the angular unit changes in sequence. Memory Calculations This calculator has one independent memory (M). It is available 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 pressing 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 entering 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 converted, a residual may occur.
