How to retain precision in the Sql Server Table column data type 'float' when using SqlBulkCopy?

How do I ensure that SqlBulkCopy saves "float" values as given in the datatable instead of saving their approximations? It can be seen in the attachments that Sql Server supports saving the value on using simple insert statements or dapper's dynamic parameters. I want to take advantage of the efficiency of SqlBulkCopy class to save data from a datatable to the SQL Server. Unfortunately changing the database table column data type to "Float(2)" or "Real" is not an option. Only "Float" is allowed for compatabilty reasons. Generally the tool I am working on is used for database versioning purposes. I have alternatives like Dapper's Insert Multiple Rows which is slow compared to SqlBulkCopy. And commercial tools are not an option.
