Operation
before the last two digits (for financial
calculations).
With the switch set to 0, 2, 3, or 4, the
display shows the selected number of
digits to the right of the decimal point.
With the switch set to F (full display),
the display shows as many numbers
to the right of the decimal point as
possible.
For example (with 5/4 .set to .),
when you divide 22 by 7:

CALCULATION
ERRORS
E (error) appears on the display
when:
• A calculation result exceeds 12
digits (this is an overflow error —
see
“Estimating Calculation
Results”).
• A memory calculation exceeds
12 digits.
• You attempt to divide by 0.
• You attempt to calculate the
square root of a negative num
-
ber.
If an overflow error occurs, E ap-
pears. To clear E from the display
(without deleting numbers from mem
-
ory), press CE.
If the error occurs in a memory calcu-
lation, M (memory) flashes and E ap-
pears. To clear E from the display,
press
ON/AC. This also clears the
memory.
To clear an error caused by trying to
calculate the square root of a nega
-
tive number or by trying to divide by 0,
press
ON/AC. This also clears the
memory.
Estimating Calculation
Results
If your calculation results in an over-
flow error, you can estimate the ap-
proximate result by following these
steps.
1. Count the number of digits dis-
played to the left of the decimal
point.
2. Remove the decimal point.
3. Add as many zeros to the right of
the number as there were digits
to the left of the decimal point.
