超大整数相乘算法的VB实现与源代码分析，可以显示执行过程，运算速度快，有一个特点就是乘数和被乘数都必须是数字，没有涉及更高深的理论，有需要的研究一下。-Large integer multiplication algorithm with the VB source code analysis can show the process of implementation, operation speed, there is a characteristic of the multiplier and the multiplicand must be digital, there is no more deeply involved in the theory, there is a need to find out.
