[. . . ] · Recurring decimal value input can be performed regardless of the Rdec setting on the setup menu. Displaying a Calculation Result as a Recurring Decimal Value Calculation results that can be displayed as recurring decimal values will be displayed as such when ON is selected for the Rdec setting on the setup menu. Pressing the key will cycle between the available calculation result formats as shown below.

Each value and the decimal point require one byte, and each digit of the period requires one byte. The following, for example, would require of total of 8 bytes (4 bytes for the values, 1 byte for the decimal · · point, 3 bytes for the period): 0. 123 Note: For information about switching the display format of a calculation result when OFF is selected for the Rdec setting on the setup menu, see "Toggling Calculation Results".

To assign the result of 3 + 5 to variable A 3 5 To multiply the contents of variable A by 10 (Continuing) To recall the contents of variable A To clear the contents of variable A (STO) (A) 8 80 (A) 10 (A) (A) (Continuing) 0 (STO) 8 0 E-16 Independent Memory (M) You can add calculation results to or subtract results from independent memory. The "M" appears on the display when there is any value other than zero stored in independent memory.

Clearing the Contents of All Memories Ans memory, independent memory, and variable contents are retained even if you press , change the calculation mode, or turn off the calculator. Perform the following procedure when you want to clear the contents of all memories. (CLR) (Memory) (Yes) Prime Factorization In the COMP Mode, you can factor a positive integer up to 10 digits into prime factors up to three digits. To perform prime factorization on 1014 1014 (FACT) When you perform prime factorization on a value that includes a factor that is prime number with more than three digits, the part that cannot be factored will be enclosed in parentheses on the display. To perform prime factorization on 4104676 (= 22 (FACT) Any one of the following operations will exit prime factorization result display. · Using the setup menu to change the angle unit setting (Deg, Rad, Gra) or the display digits setting (Fix, Sci, Norm). Note: · You will not be able to execute prime factorization while a decimal value, fraction, or negative value calculation result is displayed. · You will not be able to execute prime factorization while the result of a calculation that uses Pol, Rec is displayed. 10132) E-17 Function Calculations For actual operations using each function, see the "Examples" section following the list below. [. . . ] Syntax ERROR Cause: There is a problem with the format of the calculation you are performing. Insufficient MEM Error Cause: The configuration of TABLE Mode parameters caused more than 30 X-values to be generated for a table. Action: Narrow the table calculation range by changing the Start, End, and Step values, and try again. Argument ERROR Cause: A non-integer argument was input for the random number function (RanInt#).
