Clearing the Contents of All Memories
Ans memory, independent memory, and variable contents are retained even
if you press

Prime Factorization
In the COMP Mode, you can factor a positive integer up to 10 digits into
prime factors up to three digits.

(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.

• 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.
