本文整理了Java中org.apache.poi.ss.usermodel.Cell.getNumericCellValue()方法的一些代码示例，展示了Cell.getNumericCellValue()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Cell.getNumericCellValue()方法的具体详情如下：
包路径：org.apache.poi.ss.usermodel.Cell
类名称：Cell
方法名：getNumericCellValue
[英]Get the value of the cell as a number.
For strings we throw an exception. For blank cells we return a 0. For formulas or error cells we return the precalculated value;
[中]以数字形式获取单元格的值。
对于字符串，我们抛出一个异常。对于空白单元格，我们返回0。对于公式或误差单元格，我们返回预先计算的值；
