关于浮点运算的著述很多,有的还附有程序,但本文主要是对现有的Intel 8080/8085浮点软件包在工业控制应用时发现的问题和对其改进的一点体会。8080/8085机虽然推出较早,但在工业控制系统中应用还大有前途,因此本文对应用者有一定参考价值。改进后的浮点软件包,只增加了二个数据形式转换程序,就解决了通信或外部设备的十进制符号代码运算的问题。改进后的浮点库,在原来的基础上更加完善,已用于某工业控制系统的数据处理,获得令人满意的效果。
There are a lot of books on floating-point arithmetic, some of them are accompanied by programs, but this article is mainly about the problems found in the industrial control applications of the existing Intel 8080/8085 floating point software package and some improvements on it. 8080/8085 machine although introduced earlier, but in the industrial control system is still promising, so this article has some reference value for the user. The improved floating-point software package only adds two data format conversion programs and solves the problem of computing the symbolic code in decimal notation of communication or external devices. The improved floating point library, based on the original more perfect, has been used in an industrial control system for data processing, access to satisfactory results.
