大数运算实现的相关技术研究

Research on the Relevant Technologies for the Implementation of Large Number Operations

根据普通计算数的表示问题和溢出带来的问题,本文试图解决大数计算数的表示问题以及大数计算溢出的处理方法,就此提出了ADLNO(Algorithmic Design of Large Number Operation)算法,动态调整字长,突破传统字长限制,设计出DLNC(Design of Large Number Computing)大数运算模型,实现了大数有关计算。本实验设计的DLNC大数计算模型实现了大数计算的基本功能,和java大数运算相比较,计算速度更快,在大数算法上具有一定的优越性。

According to the problem of representation and overflow of common computational numbers,this paper solves the problem of representation of large computational numbers and the processing method of large computational overflow.In this regard,ADLNO algorithm is proposed to dynamically adjust word length and break through the limitation of traditional word length.DLNC large computational model is designed to realize large computations.This experiment realizes the basic function of large number calculation,and puts forward DLNC large number calculation model.Compared with Java large number calculation,the calculation speed is faster,and it has certain advantages in large number algorithm.
