POCKET REFERENCE GUIDE — 11

FRACTIONAL SETTINGS Setting Fractional Accuracy

When your calculator is in a default condition (battery change or full reset), it is set to round fractional values to the nearest 1/16th of an Inch. The fractional level can be revised by using the following keystrokes:

Ç 1 = Accuracy set to 1/16” Ç 2 = Accuracy set to 1/2” Ç 3 = Accuracy set to 1/32” Ç 4 = Accuracy set to 1/4” Ç 6 = Accuracy set to 1/64” Ç 8 = Accuracy set to 1/8”

A star (★) will appear in the bottom left of the display when the calculator is turned on, if the setting is different from the default. The fractional setting can be displayed at any time by pressing ® /.

Normal Fractional Mode

The default,

Normal Mode

(Ç 7), reduces a fraction to its lowest common denominator (for example, 8/16 rounds to 1/2). If a fraction is entered having a higher fractional accuracy than the current setting, the setting will be temporarily revised to the level of accuracy of the entered value.

POCKET REFERENCE GUIDE — 12

Fixed Fractional Mode

In the

Fixed Mode

(Ç 9), fractional results are displayed in the set fractional value, not reduced. Entries of higher accuracy values will be rounded to the nearest Fraction of the accuracy setting (for example, for a Fraction level setting of 1/16, an entry of 5 / 3 2 = will result in a display of 3/16).

ENTERING DIMENSIONS Linear Dimensions

When entering Feet-Inch values, enter dimensions from largest to smallest — Feet before Inches, Inches before Fractions. Enter Fractions by entering the numerator (top), pressing / (Fraction Bar key) and then the denominator (bottom).

Note: If a denominator is not entered, the fractional setting value is used.

Examples of how linear dimensions are entered:

BASIC MATH OPERATIONS

Your calculator uses standard chaining logic, which simply means that you enter your first value, the operator (+, –, x, ÷), the second value and then the Equal sign (=).

A. 3 + 2 = 5 B. 3 – 2 = 1 C. 3 x 2 = 6 D. 3 ÷ 2 = 1.5

This feature also makes the calculator simple to use for dimensional applications:
