            Description

            For example, return types of AVG() is the input type. So, if the input is INT/BIGINT type, AVG() is always truncated. Depending on the database, some database follow this behavior while others (e.g. Oracle/MySQL/etc.) do not and return floating point values for AVG().

            Similar for other functions mentioned here.
