“四舍六入五单双”在土工试验中的应用

Application of "below 4-canceling,above 6-adding,and equal 5-keep" in soil test

结合《数值修约规则与极限数值的表示和判定》中的修约法则,介绍了"四舍六入五单双"自定义函数在土工试验数约修约中的应用,指出该方法在工程实际计算中简单方便,能大大提高工作效率,值得推广。

Combining with the modification law of Numerical Value Rounding And Expression Way And Judgment Of Numerical Value Limit, it introduces the application of ＂below 4-canceling, above 6-adding, and equal 5-keep＂ user-defined functions in soil testing modification value, and points out the advantages of this method, which is easy to calculate, can improve working efficiency, and is worth to be popularized.
