1.3 Basic Set Up This section tells you how to perform basic set up required by the calculator. In addition to the procedures provided here, you can also use the set up displays (page 21) to set up the calculator. • Default Unit of Angular Measurement lornonmEnart EEEEEE The following are the items that are available from this menu. E (Deg) FY (Rad) Fa (Gra) E(o) E(r) E(9) Degrees (default angular measurement unit) Radians (default angular measurement unit) Grads (default angular measurement unit) Degrees (input value) Radians (input value) Grads (input value) Example To set the default unit of angular measurement as degrees (Deg). IMEMEMEMEMI F1 (Deg) IDes e' •The relationship between the angular measurement units is shown below., r, 360° = 2r radians = 400 grads 90° = 7r/2 radians = 100 grads IllAbout the DISP Menu Use the DISP Menu to specify the number of decimal places, the number of significant digits, and the display format. You can also use it for engineering calculations. I rifiEMEIBEICErresigriai EEEEEE ID (Fix) FY (Sci) Displays &screen for specification of the number of decimal places: Displays a screen for specification of the number of significant Fa (Nrm) Switches the display fOrmat between Norm 1 and Norm 2. -28- E(Eng) E(ENG) Fs (ENG) Engineering mode Shifts decimalplace three places to the right, and adds 3 to the exponent. Shifts decimal place three places to the left, and subtracts 3 from the exponent. •The ENG and ENG menu options appear only when there is a calculation result shown on the display. • To specify the number of decimal places Example To set the number of decimal places to 2 giragii Fl (Fix)0 'Fix 2 •With the above setting (two decinial places), all displayed values are rounded off to two decimal places. •You can input any single-digit value in the range of 0 to 9 to specify the number of decimal places. *Note that the number of decimal places setting is cancelled whenever you switch between the Norm 1 and Norm 2 display formats (see page 60). Important The specification for the numberof decimal places is applied to the diSplayed value only. The calculator still stores the entire 15-digit mantissa and 2-digit exponent of the result in memory. If you change the number of decimal places specification while a calculation result is displayed, the display changes to show the result using the new specification. • To specify the number of significant digits Example To set the number of significant digits to 3 ISci 3 O. 00E+00I •With the above setting (three significant digits), all di played values will be shown with three significant digits. •You can input any single-digit value in range of 0 to 9 to specify the number of sig -29-
