C语言中浮点数精度问题分析

Analysis on Precision of Floating-point Number for C Language

通过实例直观地描述了C语言中由于计算机存储数据方式的不同而造成的数据误差,并对误差产生的原因进行了分析,解读出C语言中浮点型数据的不同存储方式,最后给出几点建议。

This article describes how data errors are caused in C language due to different data storage method with case study, an-alyses the reason for such errors and explains different storage methods of floating point data in C language. Finally, some sugges-tions are proposed in this article.
