单片机C语言编程中多位乘法运算问题探讨

Study of Multiplicative Prog Ramming Problem in C51

本文指出了人们运用C51实现多字节乘法运算时可能忽视的一个问题.通过分析该问题出现的原因,提出了中间变量法、分步运算法和强制数据类型转换法等3种解决方法,实验表明这些方法是可行的.

This text points out a problem that people may neglect in the use of C51 to operate multiplication of multi-bytes. It analyzes the reason why this prodlem appears. Then it puts forward three methods to resolve it, and these methods are proved to be feasible by experiments.
