, the

display shows the selected number of
digits to the right of the decimal point.

With the switch set to

(full display),

the display shows as many numbers
to the right of the decimal point as
possible.

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

from the display

(without deleting numbers from mem-

E

from the display,

press

. 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

. 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.
