指定要存储在Excel文件中的有效数字位数

可能的使用场景

默认情况下,Aspose.Cells在电子表格中存储双精度值的17个有效数字,而Excel应用程序仅存储15个有效数字。您可以更改Aspose.Cells的默认行为,即您可以在使用CellsHelper.SignificantDigits属性时将有效数字位数从17更改为15。

指定要存储在Excel文件中的有效数字位数

以下示例代码强制Aspose.Cells在存储Excel文件中的双精度值时使用15个有效数字。请检查输出Excel文件。更改其扩展名为.zip并解压缩,您将会看到,该Excel文件中只存储了15个有效数字。以下屏幕截图解释了CellsHelper.SignificantDigits属性对输出Excel文件的影响。

示例代码

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java
// The path to the documents directory.
String dataDir = Utils.getSharedDataDir(SignificantDigits.class) + "CellsHelperClass/";
//By default, Aspose.Cells stores 17 significant digits unlike
//MS-Excel which stores only 15 significant digits
CellsHelper.setSignificantDigits(15);
//Create workbook
Workbook workbook = new Workbook();
//Access first worksheet
Worksheet worksheet = workbook.getWorksheets().get(0);
//Access cell A1
Cell c = worksheet.getCells().get("A1");
//Put double value, only 15 significant digits as specified by
//CellsHelper.SignificantDigits above will be stored in excel file just like MS-Excel does
c.putValue(1234567890.123451711);
//Save the workbook
workbook.save(dataDir + "out_SignificantDigits.xlsx");
