《ＭＣＳ－５１单片机实用子程序库（９６年版）》周航慈

目前已有若干版本的子程序库公开发表，它们各有特色。笔者在1988年也编制了两个

子程序库（定点子程序库和浮点子程库），并在相容性、透明性、容错性和算法优化方面作了一些工作。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。（转）-"MCS-51 microcontroller practical Subroutine Library (96)" Hang Zhou chee There are a number of versions of the son the procedure is published their own characteristics. The author in 1988 also produced two subroutine library (fixed-point and floating-point subroutine library son-Treasurer), and compatibility, transparent, fault tolerance and optimization algorithm has done some work. The procedures for the open square algorithm for the rapid study author approximation algorithm, it will reach Newton iteration of the same precision, and the speed around 20 times, more than double byte sentinel division of speed. After eight years of the country's actual use of user feedback a lot of information, gradually expanding the number of new subroutine, corrected some mistakes implied
