User manual CASIO AL-100R

[. . . ] · Be sure to keep all user documentation handy for future reference. Sample Operations Sample operations in this manual are indicated by a icon. Unless specifically stated, all sample operations assume that the calculator is in its initial default setup. Use the procedure under "Initializing the Calculator" to return the calculator to its initial default setup. For information about the B, b, v, and V marks that are shown in the sample operations, see "Configuring the Calculator Setup". Initializing the Calculator Perform the following procedure when you want to initialize the calculator and return the calculation mode and setup to their initial default settings.

To switch a calculation result between improper fraction and mixed fraction form: Perform the following key operation: 1f(<) To switch a calculation result between fraction and decimal form: Press f. Percent Calculations Inputting a value and pressing 1((%) causes the input value to become a percent. 150 × 20% = 30 150 * 20 1((%)= 30 75 2875 2625 Calculate what percentage of 880 is 660. (2625) 3500 - 3500 * 25 1((%)= Degree, Minute, Second (Sexagesimal) Calculations Performing an addition or subtraction operation between sexagesimal values, or a multiplication or division operation between a sexagesimal value and a decimal value will cause the result to be displayed as a sexagesimal value. The following is the input format for a sexagesimal value: {degrees} $ {minutes} $ {seconds} $. Note: You must always input something for the degrees and minutes, even if they are zero. 2°20´30 + 39´30 = 3°00´00 2 $ 20 $ 30 $+ 0 $ 39 $ 30 $= 3°0´0 Convert 2°15´18 to its decimal equivalent. 2 $ 15 $ 18 $= 2°15´18 (Converts sexagesimal to decimal. ) $ 2. 255 (Converts decimal to sexagesimal. ) $ 2°15´18 Multi-Statements You can use the colon character (:) to connect two or more expressions and execute them in sequence from left to right when you press =. E-14 3+3:3×3 3 + 3 SW(:) 3 * 3 = = 6 9 Using Engineering Notation A simple key operation transforms a displayed value to engineering notation. Transform the value 1234 to engineering notation, shifting the decimal point to the right. 1234 1234 = W 1. 234×103 W 1234×100 Transform the value 123 to engineering notation, shifting the decimal point to the left. · If a ÷R calculation is part of a multi-step calculation, only the quotient is passed on to the next operation. (Example: 10 + 17 !D (÷R) 6 = 10 + 2) · Operation of the f and e keys is disabled while a remainder division result is on the display. Cases when Remainder Division becomes Non-remainder Division If either of the following conditions exists when you perform a remainder division operation, the calculation will be treated as normal (non-remainder) division. · When either the dividend or the divisor is a very large value Example: 20000000000 !D(÷R) 17 = Calculated as: 20000000000 ÷ 17 · When the quotient is not a positive integer, or if the remainder is not a positive integer or positive fractional value Example: - 5 !D(÷R) 2 = Calculated as: ­5 ÷ 2 Function Calculations For actual operations using each function, see the "Examples" section following the list below. : is displayed as 3. 141592654, but = 3. 14159265358980 is used for internal calculations. e : e is displayed as 2. 718281828, but e = 2. 71828182845904 is used for internal calculations. Input a function from the menu that appears when you perform the following key operation: 1G(DRG'). Note that the input method is different depending upon whether you are using Natural Display or Linear Display. The & key also can be used for input, but only while Natural Display is selected. See 2 3 -1 6. x , x , x^, ), #, ", x : Powers, power roots, and reciprocals. Note that the input methods for x^, ), #, and " are different depending upon whether you are using Natural Display or Linear Display. See 7. Note: The following functions cannot be input in consecutive sequence: x2, x3, x^, x-1. Pol, Rec : Pol converts rectangular coordinates to polar coordinates, while Rec converts polar coordinates to rectangular coordinates. [. . . ] Insufficient MEM Error Cause: An attempt to generate a number table in the TABLE Mode whose conditions cause it to exceed the maximum number of allowable rows. The maximum number of rows is 30 when "f(x)" is selected for the setup menu table setting and 20 when "f(x), g(x)" is selected. Action: Narrow the table calculation range by changing the Start, End, and Step values, and try again. E-28 Argument ERROR Cause: A non-integer argument was input for the random number function (RanInt#). Action: Input only integers for the argument. Before Assuming Malfunction of the Calculator. . . Perform the following steps whenever an error occurs during a calculation or when calculation results are not what you expected. [. . . ]
