9*44=396位乘8位,包含显示用时,这样的速度可比傅利叶快速变换大数乘法?

谢谢！是不慢，原理是啥？是vb版程序吗？希望指点一下！

刚设计出来的,新鲜出炉,看我博客,C++的,尚未转写VB,看得懂就自己去转写.
先用其他的程序验证一下答案是否正确,还要优化.

原理就是我发的构思

    大整数8位乘法("99999999","99999999");

    大整数8位乘法("99999999999999","99999999");出错了丢失了1前面的0了.需要设法解决,理论和实践我的构思是可行的,也是计算正确的,有点小意外要处理,不是计算错误.
更新博客,后续程序还要优化,暂时解决了丢失0的问题,这个博客更新有点问题,排版格式不对,只好删除了先前的博客,重新发布.

谢谢！我看不懂vc，小的数据看不出是否速度提高了，我的程序也是达到10^（-2）～10^（-3）之间，数量级不变，只有计算更大的数才能分辨！非常感谢！

那给个例子来运行试看.
