Abstract

PURPOSE:To prevent an erroneous answer and to make a printed list easy to see, by enclosing a numeral with brackets when the result of operation is negative, in a calculator with program possible for manual computation. CONSTITUTION:If an ANS code discriminating circuit 17 detects that the result of operation is negative, a reset signal d is outputted to a flip-flop 42 from a CPU12 to reset an ANS flag. As a result, parentheses are added after the operation of a key. Thus, the operation using the numeral itself including signs can be obtained independently of the sign of result of operation, allowing to avoid erroneous answer.
