The previous calculation result will not be recalled after entering multiple instructions. ª100000/3= @i 2 @i. 33333. 33333 33333. 33 3. 33 04 33333. 33333 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: · 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 (°) 123. 404080 degree minute Note: When the calculation or conversion result is converted, a residual may occur. second Press G GRAD (g) RAD (rad) Coordinate Conversions · Before performing a calculation, select the angular unit. Y y 0 x X P (x, y) Y P (r, ) r 0 STATISTICAL CALCULATIONS Press @ Æ to select statistics mode. The following statistics can be obtained: x sx x n x x2 Mean of samples (x data) Sample standard deviation (x data) Population standard deviation (x data) Number of samples Sum of samples (x data) Sum of squares of samples (x data) X Rectangular coord. Polar coord. BINARY, OCTAL, DECIMAL, AND HEXADECIMAL OPERATIONS (N-BASE) This calculator can perform the four basic arithmetic operations, calculations with parentheses and memory calculations using binary, octal, decimal, and hexadecimal numbers. 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. Ï î : Converts to the octal system. Ï ì : Converts to the hexadecimal system. 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: F A B C D E Data Entry and Correction Entered data are kept in memory until @ Æ or F are pressed. Before entering new data, clear the memory contents. [Data Entry] Data k Data * frequency k (To enter multiples of the same 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 or @ J 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 × 10100. · an attempt is made to take the square root of a negative number. A å, B , C ç, D , E é, F 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.
