实现大整数乘积精确值的一个算法

An Algorithm on Gaining the Precise Numerical Value of Long-number Multiplication

运用叠加算法把大整数按3位分解求得乘积,大整数以及乘积结果以字符形式表示,并以两个多位数相乘为例,用VB编程给出实例求出了精确的乘积结果,分析了该算法的优点。

It receives product through dividing Long-number into 3-digit with pen-and-pencil method,the Long-number and multiplication results are expressed by the form of character.Taking two Long-numbers for example,it gets the exact results by VB and analyzes the advantages of this method.
