User manual CASIO AL-100R

[. . . ] shall not be liable for any claim of any kind whatsoever by any other party arising out of the use of this product and the items that come with it. · 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. [. . . ] 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. 123 123 = 1W() 0. 123×103 1W() 0. 000123×106 Calculation History In the COMP Mode, the calculator remembers up to approximately 200 bytes of data for the newest calculation. You can scroll through calculation history contents using f and c. 1+1=2 2+2=4 3+3=6 1+1= 2+2= 3+3= (Scrolls back. ) f (Scrolls back again. ) f 2 4 6 4 2 Note: Calculation history data is all cleared whenever you press O, when you change to a different calculation mode, when you change the display format, or whenever you perform any reset operation. Replay While a calculation result is on the display, you can press d or e to edit the expression you used for the previous calculation. 4 × 3 + 2. 5 = 14. 5 b 4 * 3 + 2. 5 = 4 × 3 - 7. 1 = 4. 9 (Continuing) dYYYY- 7. 1 = 14. 5 4. 9 Note: If you want to edit a calculation when the ' indicator is on the right side of a calculation result display (see "Reading the Display"), press A and then use d and e to scroll the calculation. Answer Memory (Ans)/Previous Answer Memory (PreAns) The last calculation result obtained is stored in Ans (answer) memory. The calculation result obtained prior to the last one is stored in PreAns (previous answer) memory. Displaying the result of a new calculation will move current Ans memory contents to PreAns memory and store the new calculation E-15 results in Ans memory. · 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. E-18 sin, cos, tan, sin-1, cos-1, tan-1 : Trigonometric functions. Specify the angle unit before performing calculations. sinh, cosh, tanh, sinh-1, cosh-1, tanh-1 : Hyperbolic functions. Input a function from the menu that appears when you press w. The angle unit setting does not affect calculations. °, r, g : These functions specify the angle unit. ° specifies degrees, r radians, and g grads. Input a function from the menu that appears when you perform the following key operation: 1G(DRG'). See 3. $, % : Exponential functions. [. . . ] If the calculator discovers any abnormality, it automatically initializes the calculation mode and clears memory contents. For details about initialized settings, see "Configuring the Calculator Setup". Initialize all modes and settings by performing the following operation: 19(CLR)1(Setup)=(Yes). Replacing the Battery A low battery is indicated by a dim display, even if contrast is adjusted, or by failure of figures to appear on the display immediately after you turn on the calculator. If this happens, replace the battery with a new one. [. . . ]
