1. To access format options, press & |. The DEC indicator

appears with the selected number of decimal places.

2. To change the number of decimal places displayed, key in a value

and press !.

3. To access another calculator format, press # or " once for each

format.

For example, to access the angle unit format, press #. To access the

number-separator format, press " " "or # # #.

4. To change the selected format, press & V.

5. To change another calculator format, repeat step 3 and step 4.

Choosing the Number of Decimal Places Displayed

The calculator stores numeric values internally to an accuracy of 13 digits,

but you can specify the number of decimal places you want to display.

The calculator displays up to 10 digits with the floating-decimal option.

Results exceeding 10 digits appear in scientific notation.

You can change these calculator formats:

Changing the number of decimal places affects the display only. Except

for amortization and depreciation results, the calculator does not round

internal values. To round the internal value, use the round function. (See

“Rounding & o” on page 10.)

Note: All examples in this guidebook assume a setting of two decimal

places. Other settings might show different results.

Choosing the Angle Units

The angle unit value affects the display of results in trigonometric

calculations. When you select radians, the RAD indicator appears in the

upper right corner of the display. No indicator appears when you select

the default setting of degrees.

Using Dates

The calculator uses dates with the Bond and Date worksheets and the

French depreciation methods. To enter dates, use this convention:

mm.ddyy (US) or dd.mmyy (European). After you key in the date, press

 

Choosing Calculation Methods

When you choose the chain (Chn) calculation method, the calculator

solves problems in the order that you enter them. (Most financial

calculators use Chn.)

For example, when you enter 3 H 2 < 4 N, the Chn answer is 20 (3 + 2 = 5,

5 * 4 = 20).

Using AOSé (algebraic operating system), the calculator solves problems

according to the standard rules of algebraic hierarchy, computing

multiplication and division operations before addition and subtraction

operations. (Most scientific calculators use AOS.)

For example, when you enter 3 H 2 < 4 N, the AOS answer is 11 (2 Q 4 =

8; 3 + 8 = 11).
