MCS-51单片机实用子程序库，本程序库中的开平方算法为笔者研究的快速逼近算法，它能达到牛顿迭代法同样的精度，而速度加快二十倍左右，超过双字节定点除法的速度。经过八年来全国广大用户的实际使用，反馈了不少信息，陆续扩充了一些新的子程序，纠正了一些隐含错误，成为现在这个最新版本。-MCS-51 single-chip utility subroutine library, the library of the square root algorithm for fast approximation algorithm for the author the study, it can achieve the same precision Newton iteration, which is about twenty times faster, than double-byte fixed-point division speed. After eight years of actual use of the vast number of users, a lot of feedback information, have expanded the number of new routines to correct some wrong implied

Mistakenly become now this latest version.
