因为工作的需要，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。-Because the needs of work, to achieve single-chip open radical operation. Square root of the current methods are mostly used Newton iteration. I checked some information in the future than to find a more rapid Newton iteration method. Dare not exclusive to introduce to you the hope that it might be useful.
