Use Format (member_price,10), TRUNCATE (member_price,10), ROUND (member_price,10) and other functions to query if through Resultset.getlong () To get the value of the query, and finally get only one decimal, you need to use resultset.getstring () to get the exact query results .Conclusion: It is best not to use the float
