packed byte

基本解释

We could have packed more information into each byte, but it would have obscured the purpose of the example.
我们本来可以在一个字节中包含更多的信息，但是这样可能会使这个例子的本意变得模糊。
The carry from bit3 to bit4 needed for adding packed binary coded decimal number correctly, where two binary coded decimal digits reside in one8-bit byte.
二进制编码的十进制数进行相加所需的从第3位到第4位的进位。
The carry from bit3 to bit4 needed for adding packed binary coded decimal number correctly, where two binary coded decimal digits reside in one8-bit byte.
在两个用二进位编码的十进位数字字同居于一个8位元位元组内的情况下，为了正确地对装配型二进位编码的十进位数字进行相加所需的从第3位到第4位的进位。
