How to display very long numbers in a cell without rounding off in C#, VB.NET?
2 mins read
This article explains how to display very long numbers without rounding off in XlsIO.
Microsoft Excel displays all digits of a numeric value in the cell if its digit count does not exceed the maximum count, with respect to system resolution. Otherwise it is displayed in exponential format and displayed. This is same in XlsIO and is not possible to retrieve the entire cell value as entered, through DisplayText. Therefore, the cell’s number format should be set to text to retrieve the number as entered.
To know more about applying number formats, please refer the documentation.
The following C#/VB complete code snippet explains how to display very long numbers without rounding off using XlsIO.
C#
using Syncfusion.XlsIO;
using System.IO;
namespace LongNumber_WithoutRounding
{
class Program
{
static void Main(string[] args)
{
using (ExcelEngine excelEngine = new ExcelEngine())
{
IApplication application = excelEngine.Excel;
application.DefaultVersion = ExcelVersion.Excel2013;
//Create a new workbook
IWorkbook workbook = application.Workbooks.Create(1);
//Accessing first worksheet in the workbook
IWorksheet worksheet = workbook.Worksheets[0];
//Entering a long number with text number format
worksheet.Range["A1"].NumberFormat = "@";
worksheet.Range["A1"].Value = "1234567890987654321";
//Autofit column to view view entire cell contents
worksheet.AutofitColumn(1);
//Saving the workbook as stream
Stream outputStream = File.Create("Output.xlsx");
workbook.SaveAs(outputStream);
}
}
}
}
VB
Imports System.IO
Imports Syncfusion.XlsIO
Namespace LongNumber_WithoutRounding
Class Program
Private Shared Sub Main(ByVal args() As String)
Using excelEngine As ExcelEngine = New ExcelEngine
Dim application As IApplication = excelEngine.Excel
application.DefaultVersion = ExcelVersion.Excel2013
'Create a new workbook
Dim workbook As IWorkbook = application.Workbooks.Create(1)
'Accessing first worksheet in the workbook
Dim worksheet As IWorksheet = workbook.Worksheets(0)
'Entering a long number with text number format
worksheet.Range("A1").NumberFormat = "@"
worksheet.Range("A1").Value = "1234567890987654321"
'Autofit column to view view entire cell contents
worksheet.AutofitColumn(1)
'Saving the workbook as stream
Dim outputStream As Stream = File.Create("Output.xlsx")
workbook.SaveAs(outputStream)
End Using
End Sub
End Class
End Namespace
