PURPOSE:To perform continuous stepwise calculation while confirming the intermediate result by inputting a previous arithmetic result as the operand of a precedent function such as a trigonometrical function when the precedent function is inputted right after arithmetic execution. CONSTITUTION:An arithmetic execution means 1 accepts the input of an operator by key operation and also accepts the input of the operand obtained as a result of the key operation on the precedent arithmetic. A binary operator is inputted between two operands normally by an infix notation and for a unary operator, on the other hand, >=1 precedent unary operator which is inputted before the operand is set. When the arithmetic execution means 1 performs arithmetic, an arithmetic execution identification means 3 enters a state indicating arithmetic execution and when some input to the arithmetic execution means 1 is performed, a reset means resets the state of the arithmetic execution identification means 3. |
