When an explicit conversion results in a loss of scale, the results are truncated without warning. For example, when you explicitly convert a float, numeric, or decimal type to an integer, Adaptive Server assumes you really want the result to be an integer and truncates all numbers to the right of the decimal point.
During implicit conversions to numeric or decimal types, loss of scale generates a scale error. Use the arithabort numeric_truncation option to determine how serious such an error is considered. The default setting, arithabort numeric_truncation on, aborts the statement that causes the error but continues to process other statements in the transaction or batch. If you set arithabort numeric_truncation off, Adaptive Server truncates the query results and continues processing.
