calculations).

With the switch set to

, 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

**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.
