Chapter 2: General Information

The SET UP menu

The SET UP menu enables you to change the angular unit and the display format.

•Press @ J to display the SET UP menu.

•Press j to exit the SET UP menu.

Determination of the angular unit

The following three angular units (degrees, radians, and grads) can be specified.

• DEG(°) : Press @ J 0 0

•RAD (rad): Press @ J 0 1

•GRAD (g) : Press @ J 0 2

Selecting the display notation and number of decimal places

Five display notation systems are used to display calculation results: Two settings of Floating point (NORM1 and NORM2), Fixed decimal point (FIX), Scientific notation (SCI) and Engineering notation (ENG).

•When @ J 1 0 (FIX) or @ J 1 2 (ENG) is pressed, ‘TAB(0-9)?’ will be displayed and the number of decimal places (TAB) can be set to any value between 0 and 9.

•When @ J 1 1 (SCI) is pressed, ‘SIG(0-9)?’ will be dis- played and the number of significant digits (SIG) can be set to any value between 0 and 9. Entering 0 will set a 10-digit display.

•When a floating point number does not fit in the specified range, the calculator will display the result using the scientific notation (exponential notation) system. See the next section for details.

Setting the floating point numbers system in scientific notation

The calculator has two settings for displaying a floating point number: NORM1 (default setting) and NORM2. In each display setting, a number is automatically displayed in scientific notation outside a preset range:

•NORM1: 0.000000001 ≤ x ≤ 9999999999

•NORM2: 0.01 ≤ x ≤ 9999999999
