Import Excel to SharePoint List

Dear Supporter

My Sharepoint On-premises program have the import function.

When we click import button, we will select a excel file.

My program will read excel file and fill value to Sharepoint list.

We have an issue when reading data from excel:

1)      Prepare a excel file. A cell has 0.345 value 

2)      Use DocumentFormat.OpenXml library to read value

3)      Fill this value to Sharepoint list.

4)      Confirm value in SharePoint List

Actual: 

In SharePoint list will show value 0.34499999999999997

Expect: 

In SharePoint list will show value 0.345

So, I want to confirm: how I can get original value 0.345 in this case?

We investigated: 

DocumentFormat.OpenXml library read excel file and return 0.34499999999999997 value.

So, it will fill 0.34499999999999997 value to Sharepoint list.

Please help me !!!!

Thanks and best regards
