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.

Function Calculations
For actual operations using each function, see the “Examples” section
following the list below.
: P is displayed as 3.141592654, but P = 3.14159265358980 is used for
internal calculations.
e : e is displayed as 2.718281828, but e = 2.71828182845904 is used for
internal calculations.
