ERROR/OVERFLOW CONDITIONS
You
can enter up to 10 digits into the calculator. If you enter
11
or more
digits,
an
entry overflow occurs which causes the calculator to clear the first
11
digits entered and print ERROR. However, if the 12th, 13th, etc., digits
have been entered, they are accepted as part of the new entry. When this
occurs, press 1
™ and you can reenter a number that has 10 or less digits
without affecting previous entries.
Example: 123456. 7899 + 555765.4321
= 679222.222

A register overflow will also cause ERROR to be printed. If the accumulated
contents of the add registers are larger than 9999999999
(1
O digits) or
-999999999
(9 digits for negative results), ERROR
Tis
printed and the
contents of that register are automatically cleared.

ERRORG
The calculator uses
5/4
round off for 10-digit positive or 9-digit negative
results. This means that an internal result of
-999999999.4
will round off to
-999999999.
However,
-999999999.5
will round up causing an overflow. In
addition, the round off operation occurs with each entry. If the value 0.4 is
added to 5555555555, the internal result is rounded off immediately to
5555555555 again as if the 0.4 were never entered.
