为提高资料精度,水文行业规范对数字提出了“四舍六入,逢五奇进偶舍”的处理要求,工程水文分析中的数据处理基本上都是在EXECL下进行的,因此有必要掌握EXECL函数的一些计算功能,来解决水文数据处理中的“四舍六入”问题。介绍了EXECL中几个常用特殊函数在水文数据处理中的使用方法,操作简单,容易掌握,处理后的数据可用于工程水文分析计算、洪水预报等工作。
In order to improve the accuracy of data, the hydrological industry standard puts forward the processing requirement of “rounding, every odd odd even” for the figures. The data processing in engineering hydrological analysis is basically carried out under EXECL, so there is It is necessary to master some of the computational functions of EXECL functions to solve the “rounding” problem in hydrological data processing. This paper introduces the use of several commonly used special functions in hydrological data processing in EXECL. The method is simple and easy to master. The processed data can be used in engineering hydrological analysis and calculation and flood forecasting.
