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

following the list below. 
π
π
  :  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.
