2-Line Display: The first line (Entry Line) displays an entry
of up to 88 digits (or 47 digits for Stat or Constant Entry
Line). Entries begin on the left; those with more than 11
digits scroll to the right. Press

the beginning or end of the entry.

The second line (Result Line) displays a result of up to 10
digits, plus a decimal point, a negative sign, a “x10
indicator, and a 2-digit positive or negative exponent.
Results that exceed the digit limit are displayed in Scientific
Notation.

I

displays a menu to specify the Angle mode as

degrees, radians, or gradients.

=

displays a menu to specify the Angle unit modifier—

degrees (

Ä

), radians (

r

), gradients (

g

), or DMS (

Д

Е

Ж

). It

also lets you convert an angle to DMS Notation (

To set the Angle mode for any part of an entry:

¦

Select the Angle mode. Entries are interpreted and results
displayed according to the Angle mode, or

¦

Select a unit modifier (

Д

Entries with unit modifiers are interpreted accordingly,
overriding the Angle mode.

To convert an entry:

¦

Set the Angle mode to the unit you want to convert to.
