oracle - Always show decimal places in SQL? -


I am working on a query that gives numeric value (currency). Some values ​​are full numbers and are being displayed in the form of 3, 5, 2 etc., while other numbers are coming like 2.52, 4.50 etc.

How can I always force Oracle to display decimal places? / P>

thanks 

  TO_CHAR (Parma, '9, 99, 99 9. 9 ');
