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.
