+### Data rouding <!-- {docsify-ignore} -->
+When you use segment, you find that the results on the measurement line are inconsistent with the results displayed in the list. As shown below：<br>
+![](images/measure.jpg)<br>
+The lengths of the two lines on the left in the figure above are 1.01m and 2.09m respectively, and the sum of the two is 3.10m, while the list on the right shows that the sum of the lengths is 3.11m, and the two data are not equal.<br>
+The reason for this phenomenon is the rounding of the data.<br>
+
+A. The sum of the data displayed on the left measurement line is 3.10m:<br>
+1.01m is actually 1.014m, rounded to 1.01m<br>
+2.09m is actually 2.094m, rounded to 2.09m<br>
+
+B. The data in the list is the sum of the actual data of the two is 3.11m：<br>
+1.014m+2.094=3.108m，rounds to 3.11m<br>
+
+Therefore, the data of A and B are different.<br>
+This difference will not exceed the range of ±1, and the result in the list on the right shall prevail.

+### 四舍五入的数据 <!-- {docsify-ignore} -->
+当您使用连续测量，发现测量线的上的结果与列表中显示的结果不一致。如下图：<br>
+![](images/measure.jpg)<br>
+上图中左侧两条线的长度分别是1.01m和2.09m，两者之和为3.10m，而右侧列表中显示长度之和为 3.11m，两个数据不相等。<br>
+此现象产生的原因是数据的四舍五入。<br>
+
+A. 在左侧测量线上显示的数据之和为 3.10m：<br>
+1.01m实际是1.014m，四舍五入为 1.01m<br>
+2.09m实际是2.094m，四舍五入为 2.09m<br>
+
+B. 而列表中的数据是两者的实际数据之和为 3.11m：<br>
+1.014m+2.094=3.108m，四舍五入为 3.11m<br>
+
+所以导致A、B数据不同。<br>
+此差异不会超过 ±1 的范围，以右侧列表中的结果为准。
