E-15

Any one of the following operations will exit prime factorization result

display.

• Pressing !e(FACT) or =.

• Pressing any of the following keys: . or e.

• 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.

Function Calculations

For actual operations using each function, see the “Examples” section

following the list below.

: π is displayed as 3.141592654, but π = 3.14159265358980 is used for

internal calculations.

e : e is displayed as 2.718281828, but e = 2.71828182845904 is used for

internal calculations.
