计算机数补码表示法辨析

Analysis of Radix Complement Representation of Numerical Coding in Computer

计算机数补码表示法是计算机相关课程教学的重要知识点,现有教材在计算机数补码表示法描述中是雷同的。但是,笔者认为这存在一定问题,主要是补码的求解方法和补码的表示范围没有阐述清楚。参考若干资料,总结出计算机数补码几种求解方法,通过具体分析,有助于学生理解计算机数补码的表示法的本质,为计算机后序相关课程的学习打下良好的基础。

Radix complement representation of numerical coding in computer is an important knowledge point in teaching of computer courses, the descriptions of which in the teaching materials are basically the same. The author believes that the problem exists in this kind of arrangement of teaching materials. The main problem is that the calculating method and the expressing range of the radix complement are not clearly described. On the basis of study and discussion, the author has summed up several methods for calculating the radix complement, the concrete analysis in the calculation will help students understand the nature of the radix complement representation of numerical coding in computer and lay a solid foundation for their study in future computer courses.
