"二进制数调整BCD码的方法是将二进制码左移8次,每次移位后都检查低四位LSD+3是否大于7,如是则加3,否则不加,高4位MSD作同样处理"-" Binary number to adjust the BCD code is the binary code shifted left eight times, after each shift, check for a low whether four LSD+3 is greater than 7, the case of plus 3, or not added, the high-order 4 bits of MSD same treatment"
