Use Bulk Insert in SQL for decimal values

CREATE PROC spTestBulkInsertFortblTestBM (@FilePath VARCHAR(100), @FileFieldterminator VARCHAR(5))
AS
	BEGIN
		--The number of rows affected by a Transact-SQL statement will not return
		SET NOCOUNT ON;
			--Truncate the existing data from table 
			TRUNCATE TABLE dbo.tblTestBM
			--Declare the local variable
			DECLARE @bulkinsert NVARCHAR(2000) 
			 
			SET @bulkinsert =  
				   'BULK INSERT dbo.tblTestBM
				   FROM ''' +  @FilePath + ''' 
				   WITH 
				   (
				    FIRSTROW = 1,
				    FIELDTERMINATOR = '''+ @FileFieldterminator +''', 
				    ROWTERMINATOR = ''\n''
				   )' 		
			--Execute the BULK INSERT statement				   	 
			EXEC (@bulkinsert)
			--Print the number of rows affected
			PRINT CAST(@@ROWCOUNT AS VARCHAR(5))+ ' Rows Inserted'
			RETURN (@@ROWCOUNT)
		--The number of rows affected by a Transact-SQL statement will return thereafter
