要在单片机上实现开根号的操作。目前开平方的方法大部分是用牛顿迭代法。我在查了一些资料以后找到了一个比牛顿迭代法更加快速的方法。不敢独享，介绍给大家，希望会有些帮助。-To achieve square root operation on the microcontroller. Most of the square root of the current method is to use Newton iterative method. I checked some information later found a faster method than the Newton iteration method. Not exclusive, to introduce to you, I hope will be helpful.
