FRACTIONAL SETTINGS
Setting Fractional Accuracy
When your calculator is in a default condi-
tion (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 key-
strokes:
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 dis-
played 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.
4320PRG-E-A 6/16/04 7:53 AM Page 11

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 accu-
racy values will be rounded to the nearest
Fraction of the accuracy setting (for exam-
ple, for a Fraction level setting of 1/16, an
entry of 5 / 3 2 = will result in a dis-
play 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 frac-
tional 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 sim-
ple to use for dimensional applications:

any format desired, provided convention is main-
tained.
Subtracting Dimensions
Subtract 3 Feet from 11 Feet 7-1/2 Inches:

a given percent of a number or for working
add-on, discount or division percentage
calculations. It can be used with any type
of number, in any dimension (Feet, Inch,
Millimeter, etc.) and any type of convention
(non-dimensioned, Linear, Square or
Cubic).
