[. . . ] · A decimal number, variable, or exponent cannot be used in a fraction. Time, Decimal and Sexagesimal Calculations (9) Operational Notes To ensure trouble-free operation, please observe the following points: 1. o Press the RESET switch only in the following cases: · When using for the first time · After replacing the batteries · To clear all memory contents · When an abnormal condition occurs and all keys are inoperative. [. . . ] The following statistics can be obtained for each statistical calculation (refer to the table below): 6. · DISPLAY Equation Display Mantissa Symbol · 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 Single-variable statistical calculation Statistics of Exponent 1 (12) (13) (Fig. 3) Determination of the Angular Unit In this calculator, the following three angular units can be specified. DEG (°) (During actual use not all symbols are displayed at the same time. ) If the value of mantissa does not fit within the range ±0. 000000001 ­ ±9999999999, the display changes to scientific notation. The display mode can be changed according to the purpose of the calculation. / Linear regression calculation Press G GRAD (g) RAD (Radians) Statistics of and and, in addition, estimate of y for a given x (estimate y') and estimate of x for a given y (estimate x') 1 2 : Appears when the entire equation cannot be displayed. : Appears when @ is pressed, indicating that the functions shown in orange are enabled. : Indicates that h has been pressed and the hyperbolic functions are enabled. If @ H are pressed, the symbols "2ndF HYP" appear, indicating that inverse hyperbolic functions are enabled. 1 2ndF HYP SCIENTIFIC CALCULATIONS · Press @ m 0 to select the normal mode. And if the FIX, SCI, or ENG indicator is displayed, clear the indicator by pressing @ f. ALPHA: Indicates that @ K or O (R) has been pressed, and entry (recall) of memory contents and recall of statistics can be performed. FIX/SCI/ENG: Indicates the notation used to display a value and changes each time @ f are pressed. DEG/RAD/GRAD: Indicates angular units and changes each time G is pressed.
