Slide Switch Features - Victor 1280-7 Manual De Instrucciones

This section describes the mode switches, data entry keys, and operating keys provided
on your calculator. The following terms are used in discussing your calculator's
operation:
• The accumulator is the area of the calculator's logic that stores a running total of
the results of addition and subtraction operations. It is the "adding machine" portion
of the calculator.
• The calculating register is the area of the calculator's logic where the intermediate
and final results of multiplication, division and percentage calculations are stored.
The contents of the calculating register do not affect the accumulator.
• The keyboard register is the area of the calculators logic that stores the value that
will immediately be used in the next calculation.
• The item count register is the area of the calculator's logic that counts your
entries into the accumulator. Each positive entry is counted as one item. Each
Negative entry is subtracted resulting in a net item count. It is also net or gross
programmable.
• The memory register is the area of the calculator's logic that accumulates
amounts you add to or subtract from the memory. Because the memory register is
independent of the accumulator and the calculating register, it retains its value until
you clear it with the Memory Total (MT) key.

SLIDE SWITCH FEATURES

This section illustrates and describes the mode switches you can use to control your
calculator's operation.
1. A F 0 2 3 4 Decimal Point Selector
A
Monetary Add Mode: At this setting, amounts entered are assumed to
be monetary. The calculator automatically supplies a decimal point to
the left of the last two digits entered. Use this setting to add, subtract,
multiply and divide decimals.
Units/price mode operation:
Multiplication: The first factor will be entered as a whole number and
the second factor will have a decimal point supplied to the left of the
last two digits.
Division: The first factor will have a decimal point supplied to the left of
the last two digits and the second factor will be entered as a whole
number.
0,2,3,4
Fixed decimal point mode; these settings specify the number of digits
to the right of the decimal point that are shown in the result.
F
Floating decimal point mode; this setting specifies that all digits of the
result are shown up to a maximum of 12 digits. If the result exceeds
these capacities, excess digits to the right of the decimal point are
dropped. No rounding takes place.
