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 在两个用二进制编码的十进制数字同居于一个8位字节内的情况下,为了正确地对装配型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。

To resolve the behavior , most programmers either ensure that the value is greater or less than what is needed , or they get and use a binary coded decimal library that will maintain the precision 为解决此行为,大多数程序员或是确保值比需要的大或者小,或是获取并使用可以维护精度的二进制编码的十进制( bcd )库。
All the standard windows encodings are supported , as well as iso encodings , apple macintosh encodings , extended binary code decimal interchange code ( ebcdic ) , and several proprietary encodings 所有标准的windows编码标准,以及iso编码、 applemacintosh编码、 extendedbinarycodedecimalinterchangecode ( ebcdic )和几种专有编码标准都得到了支持。
