二进制转换为BCD码是不直接的,反之也一样。二进制变换成BCD码,首先是把二进制数转换成十进制数,然后,再由十进制数转换成BCD码;而BCD码要转换为二进制数,也是首先把BCD码转换成十进制数,然后,再由十进制数转换成二进制数。可见,二进制与 Binary conversion to BCD code is not direct, and vice versa. Binary code into BCD, the first is to convert the binary number into decimal numbers, and then converted to BCD decimal numbers; BCD code to be converted to binary numbers, but also the first BCD code into decimal numbers, and then by Decimal numbers are converted to binary numbers.
