中职计算机专业基于VFP编程运算错误学习计算机数据

The Computer Data Based on VFP Programming Operational Error in Computer Specialty of Secondary Vocational Schools

"万能的计算机是不会出现计算错误的"。但实际上,依然存在程序运行后无法得到正确数值的情况。其中,小数运算就是一个典型的例子。本文论述计算机进行小数处理的机制,并了解计算机在运算时为什么会出错,以及应该如何避免出错。

"A universal computer will not make mistakes in calculation.".But in fact,there are still cases when the program cannot get the correct value after running.Among them,decimal operation is a typical example.This paper discusses the mechanism of decimal processing by computer,and understands why computers make mistakes in operation and how to avoid them.
