For clean data, this is the same as converting to an integer. Casting is allowed in most contexts in which a general expression is allowed, including the WHERE clause. The default scale is 0 and so 0 <= s <= p. Maximum storage sizes vary, based on the precision. These cases will occur if the result is too short to display. What is the correct way to screw wall and ceiling drywalls?
