• NORM 1

With NORM 1, exponential notation is automatically used
for integer values with more than 10 digits and decimal
values with more than two decimal places.

• NORM 2

With NORM 2, exponential notation is automatically used
for integer values with more than 10 digits and decimal
values with more than nine decimal places.

• All of the examples in this manual show calculation re-

sults using the NORM 1 format.

Answer Memory

• Whenever you press 

=

 after inputting values or an ex-

pression, the calculated result is automatically stored in
Answer Memory. You can recall Answer Memory con-
tents by pressing 

g

.

• Answer Memory can store up to 12 digits for the mantissa

and two digits for the exponent.

• Answer Memory contents are not changed if the opera-

tion performed by any of the above key operations re-
sults in an error.
