Field Group
General
Valid Settings
The rounding behavior is different depending upon the setting of the RoundHalfwayMagUp field.
| IF you set the field to… | THEN the Teradata Database system uses the rounding semantics… |
|---|---|
| TRUE | appropriate for many business applications: The magnitudes of halfway values are rounded up. Halfway values are rounded away from zero so that positive halfway values are rounded up and negative halfway values are rounded down (toward negative infinity). For example, a value of 2.5 is rounded to 3. |
| FALSE | traditional for Teradata Database: A halfway value is rounded up or down so that the least significant digit is even. For example, a value of 2.5 is rounded to 2. |
Default
FALSE
