Claims (1)

금액처리방식을 기억시키고 연산처리할 수 있는 키보드(20)와 판매연산처리(R모드) 및 처리코드값기억(P모드)를 선택하는 모드키(40)를 중앙처리장치의 포트 A와 포트 B를 통하여 접속하고 처리코드값을 기억시키는 메모리를 중앙처리장치(10)의 포트 C를 통하여 접속하여, P모드에서 키보드(20)로 부터 입력되는 소숫점 이하 연산방식 코드값을 메모리(30)의 특정번지에 기억시키고 R모드에서 %계산시에 소숫점 이하의 금액이 발생하면 메모리(30)에 기억된 코드값에 따라 소숫점이하의 금액에 대하여 올림처리, 내림처리, 반올림처리를 선택적으로 수행하는 것을 특징으로 하는 소수점이하 연산처리 선택기능을 가진 금전등록기.A keyboard 20 capable of storing and processing the amount of money processing and a mode key 40 for selecting sales operation processing (R mode) and processing code value storage (P mode) include port A and port B of the central processing unit. Through the port C of the central processing unit 10 to connect a memory for storing the processing code value, and to specify the sub-point arithmetic operation code value input from the keyboard 20 in the P mode. If the amount less than or equal to the decimal point occurs when the memory is stored in the address and the% calculation is performed in the R mode, the rounding, rounding, and rounding processes are selectively performed on the amount less than or equal to the decimal point according to the code value stored in the memory 30. A cash register with a decimal point arithmetic processing selection function. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
