This register contains carry and overflow information from integer arithmetic operations 這個寄存器存放整數(shù)運算操作的進位以及溢出信息。
It also contains carry input to certain integer arithmetic operations and the number of bytes to transfer during load and store string instructions , 它還存放某些整數(shù)運算操作的進位輸入以及加載和存儲指令(
In all integer arithmetic operations , both overflow and underflow shall be ignored . the value returned when either overflow or underflow occurs is implementation defined 在所有的整數(shù)算術運算中,溢位和不足必須被忽視.發(fā)生溢位或不足時,傳回值由實作自訂
Since arithmetic operations of large magnitude integers can not be carried out directly , a set of subroutines for large magnitude integer arithmetic operations are developed by characterizing the large integers 為了解決特大整數(shù)的表示與處理問題,本文構(gòu)造了一套字符化大整數(shù)運算系統(tǒng)。
