Discussion on Numerical Rounding Rules for Environmental Monitoring Data
The problem of rounding off numerical values may seem simple,but it is not easy to implement.Due to the lack of a unified numerical rounding method that can handle various types of data we encounter in practical work,there is a common problem of nonstandard numerical rounding in environmental monitoring reports and scientific research papers.The article expounds the connotation of numerical rounding.The first question is how many digits are retained for numerical values,and the second question is the rounding method for numbers.And put forward two basic principles of numerical rounding:accuracy and conservation.Finally,the numerical rounding rules of common data in the environmental monitoring are summarized.
