k Making Corrections During Input •Use e and r to move the cursor to the location you want. •Press [ to delete the number or function at the current cursor position. •Press A K to change to an insert cursor t. Inputting something while the insert cursor is on the display inserts the input at the insert cursor position. • Pressing A K, or = returns to the normal cursor from the insert cursor. E-8 k Replay Function • Every time you perform a calculation, the replay function stores the calculation formula and its result in replay memory. Pressing the [ key displays the formula and result of the calculation you last performed. Pressing [ again back steps sequentially (new-to-old) through past calculations. •Pressing the e or r key while a replay memory calculation is on the display changes to the editing screen. •Pressing the e or r key immediately after you finish a calculation displays the editing screen for that calculation. •Pressing t does not clear replay memory, so you can recall the last calculation even after you press t. •Replay memory capacity is 128 bytes for storage of both expressions and results. • Replay memory is cleared by any of the following actions. When you press the 5 key When you initialize modes and settings by pressing A B 2(or 3) = When you change from one calculation mode to another When you turn off the calculator. k Error Locator •Pressing r or e after an error occurs displays the calculation with the cursor positioned at the location where the error occurred. k Multi-statements A multi-statement is an expression that is made up of two or more smaller expressions, which are joined using a colon ( : ). • Example: To add 2 + 3 and then multiply the result by 4 2 + 3 p \ g -4 = 2+3 5.Disp Ans .4 20. = E-9 k Exponential Display Formats This calculator can display up to 10 digits. Larger values are automatically displayed using exponential notation. In the case of decimal values, you can select between two formats that determine at what point exponential notation is used. •To change the exponential display format, press the F key a number of times until you reach the exponential display format setup screen shown below. Fi x Sc i Nor m 1 23 •Press 3. On the format selection screen that appears, press 1 to select Norm 1 or 2 for Norm 2. uNorm 1 With Norm 1, exponential notation is automatically used for integer values with more than 10 digits and decimal values with more than two decimal places. uNorm 2 With Norm 2, exponential notation is automatically used for integer values with more than 10 digits and decimal values with more than nine decimal places. •All of the examples in this manual show calculation results using the Norm 1 format. k Decimal Point and Separator Symbols You can use the display setup (Disp) screen to specify the symbols you want for the decimal point and 3-digit separator. •To change the decimal point and separator symbol setting, press the F key a number of times until you reach the setup screen shown below. Disp 1 •Display the selection screen. 1 r E-10 •Press the number key (1 or 2) that corresponds to the setting you want to use. 1(Dot): Period decimal point, comma separator 2(Comma): Comma decimal point, period separator k Initializing the Calculator • Perform the following key operation when you want to initialize the calculation mode and setup, and clear replay memory and variables. A B 3(All) = COMPBasic Calculations k Arithmetic Calculations Use the F key to enter the COMP Mode when you want to perform basic calculations. COMP ............................................................. F 1 • Negative values inside of calculations must be enclosed within parentheses. For details, see “Order of Operations.” • It is not necessary to enclose a negative exponent within parentheses. sin 2.34 10–5 > S 2.34 e D 5 • Example 1: 3(510–9) 1.510–8 3 -5 e D 9 = • Example 2: 5(97) 80 5 -R 9 + 7 T = •You can skip all T operations before =. k Fraction Operations uFraction Calculations •Values are displayed in decimal format automatically whenever the total number of digits of a fractional value (integer + numerator + denominator + separator marks) exceeds 10. E-11 2 1 13 • Example 1: 3 5 15 13 15.00 2 C 3 + 1 C 5 = 1 2 11 • Example 2: 3 1 4 4 3 12 3 C 1 C 4 + 4 11 12.00 1 C 2 C 3 = 2 1 • Example 3: 2 C 4 = 4 2 1 • Example 4: 1.6 2.1 1 C 2 + 1.6 = 2 • Results of calculations that mix fraction and decimal values are always decimal. uDecimal - Fraction Conversion •Use the operation shown below to convert calculation results between decimal values and fraction values. • Note that conversion can take as long as two seconds to perform. 3 • Example 1: 2.75 2 (Decimal > Fraction) 4 2.75 = 2.75 2 3 4.00 11 4.00 C 11 A B 4 1 • Example 2: - 0.5 (Fraction - Decimal) 2 1 2.00 1 C 2 = C 0.500 C1 2.00 E-12 uMixed Fraction - Improper Fraction Conversion 2 5 • Example: 1 - 3 3 1 C 2 C 3 = A B A B 5 3.00 1 2 3.00 1 2 3.00 •You can use the display setup (Disp) screen to specify t...
