单片机子程序,有各种数据格式的各种数学运算.（１）按当前流行的以 IBM PC 为主机的开发系统对汇编语言的规定,将原子程序库

的标号和位地址进行了调整,读者不必再进行修改,便可直接使用。

（２）对浮点运算子程序库进行了进一步的测试和优化,对十进制浮点数和二进制浮

点数的相互转换子程序进行了彻底改写,提高了运算精度和可靠性。

（３）新增添了若干个浮点子程序（传送、比较、清零、判零等）,使编写数据处理

程序的工作变得更简单直观。-SCM subroutine, there are a variety of data formats of various mathematical operations. (1) according to the popular IBM PC as the host to the development of system requirements on the assembly language, the atomic program library and bit address labels were adjusted, the reader do not have to be modified, can be used directly. (2) floating-point subroutine library for further testing and optimization of the decimal floating-point and binary floating point conversion routines between been completely rewritten and improved the calculation accuracy and reliability. (3) The new addition of a number of floating point routines (Carrier, compare, clear, sub-zero, etc.), so that the work of preparing the data processing more intuitive.
