For details, see "Recurring Decimal Calculations". · You cannot switch from decimal form to mixed fraction form if the total number of digits used in the mixed fraction (including integer, numerator, denominator, and separator symbols) is greater than 10. Note: With Natural Display (MathO), pressing instead of after inputting a calculation will display the calculation result in decimal form. Pressing after that will switch the calculation result to recurring decimal form, fraction form or form. The form of the result will not appear in this case. Basic Calculations Fraction Calculations Note that the input method for fractions is different, depending upon whether you are using Natural Display or Linear Display. 2+1=7 3 2 6 or 2 2 3 2 4-3 1=1 2 2 4 ( 4 3 )3 3 3 1 1 1 1 1 2 2 2 2 2 7 6 7 6 76 1 2 12 Note: · Mixing fractions and decimal values in a calculation while Linear Display is selected will cause the result to be displayed as a decimal value. · Fractions in calculation results are displayed after being reduced to their lowest terms. To switch a calculation result between improper fraction and mixed fraction form: Perform the following key operation: ( ) To switch a calculation result between fraction and decimal form: Press . Percent Calculations Inputting a value and pressing become a percent. 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. · Pressing any of the following keys: or . · 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. Trying to do so will cause a math error (Math ERROR). · 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. : is displayed as 3. 141592654, but internal calculations. sin, cos, tan, sin-1, cos-1, tan-1 : Trigonometric functions. Specify the angle unit before performing calculations. [. . . ] Check the calculation expression to make sure that it does not contain any errors. Make sure that you are using the correct mode for the type of calculation you are trying to perform. If the above steps do not correct your problem, press the key. This will cause the calculator to perform a routine that checks whether calculation functions are operating correctly. [. . . ]
