Decimal fraction results (results with digits to the right of the decimal point)
that exceed
10
digits are automatically rounded up one if the 11th digit is 5 or
larger. Negative results are rounded to
9 digits in the same manner.
Example: 5
+ 3 = 1.6666666666 ..... .

reentering the number.

Multiplication and division overflow conditions are similar to the addition and
subtraction overflow conditions in that more than 10 digits in an intermediate
or final result will cause ERROR to be printed and the calculator to be
automatically reset for entry of a new problem. An entry overflow will also
cause ERROR to be printed and the sequence
[I]
™ should be used to
continue without affecting previous entries. As in addition and subtraction, a
negative result cannot be larger than
-999999999.
(9
digits).
MIXED CALCULATIONS
The previous descriptions have not considered problems that require a
combination of addition, subtraction, multiplication and division. Besides the
differences in entry methods, it is very important to remember that the
calculator internally keeps the results of multiplication and division entries
separate from addition and subtraction entries as if there are two calculators
in
one. The first example illustrates an addition and a multiplication problem
which uses the same numbers without a number being entered twice. Notice
that the calculator provides two results as if two different problems were
entered separately.
Examples: 12
+ 15 = 27, 12 x 15 = 180
