and the selling price.
31. Backspace Key. Deletes right most
character of a live entry, moving the remaining

32. Paper Advance.
On-Off Switch. Located on the side of the
calculator.
Decimal System. With the 7130/40 entries
may contain any combination of whole and
decimal digits, up to a maximum of 12 digits.
However, internally there is a 24-digit
calculating capability. With the 7150, the
maximums are 14 and 28 respectively. The
decimal setting may be changed between
calculations without affecting the accuracy of a
number entered or accumulated.
Add Mode. Set the Decimal Selector at Add
Mode (+) and the last two digits in any entry
followed by depression of the Plus, Minus,
Memory Plus or Memory Minus key will
automatically be accepted as decimals.
Exception: if an actual decimal entry is made,

when calculating extensions. With the decimal
selector at Add Mode (+), all numbers entered
followed by depression of the Times key will be
accepted as whole numbers (units) unless an
actual decimal entry is made. The last number

Extended Capacity. If a result exceeds the
12-digit output capacity but does not exceed
the 24-digit calculating capacity, (14 and 28
respectively on the 7150) then the result will
be printed and displayed in scientific notation.
For example: if a calculation result was

in scientific notation as “2.22333444555 x

.” The printer would print the amount as
“2.2233344455514,” which indicates that to
write the extended capacity amount in
standard format, the decimal point must be
moved 14 digits to the right.
NOTE: On the 7130/40, the printer will show
12 significant digits and the exponent, while
the display will show 9. On the 7150 it will be
14 and 11 respectively.
Overflow. When a live entry contains more
than 12 digits (display and print capacity) or a
write the extended capacity amount in
standard format, the decimal point must be
moved 14 digits to the right.

Overflow. When a live entry contains more
than 12 digits (display and print capacity) or a
calculation result contains more than 24 digits
(calculating capacity), (14 digits and 28 digits
on the 7150) a series of red commas will print
indicating an overflow condition. The display
will show a “0”. The entry and/or result is
automatically cleared and the calculator is
ready for further calculations. Constants and N
Counts are not affected by this overflow
condition.
Underflow. In a result or total containing a
combination of whole and decimal digits, the
decimal point will shift right, regardless of
decimal setting in order to show the 12 most
significant digits (14 on the 7150). In results
containing more than 12 whole digits (14 on
the 7150) the calculator will go into extended
(calculating capacity), (14 digits and 28 digits

Underflow. In a result or total containing a

significant digits (14 on the 7150). In results
containing more than 12 whole digits (14 on
the 7150) the calculator will go into extended
capacity.
Reverse Underflow. When a result should
normally be 0, based on the current decimal
setting, the calculator will float the result
showing as many digits as possible. For
example, the problem 2 divided by 625, with
the Decimal Selector set at (2), would yield a
result 0.00 without Reverse Underflow. With
this feature, however, a significant result of
0.0032 is given.
Automatic Calculation Mode Correction. If
you accidentally depress the Times key instead
of the Divide key (or vice-versa), it is not
necessary to clear the calculator. Merely
depress the correct function key (in this case,
the Divide key) and proceed with the
