Question & Answer
Question
Previous to IBM Cognos Business Intelligence 10.2, the product used the round half to even rule when rounding numbers. The round half to even rule is widely used in bookkeeping. However, precision regulations in some regions require different rounding rules (for example, the round half up rule). With IBM Cognos Business Intelligence, you can now choose a rounding rule to comply with the precision regulations that apply to you.
Answer
There is an advanced setting that can now be set . "RSVP.RENDER.ROUNDING"
Here are the IBM Cognos BI rounding rules and descriptions
Rule | Description |
| halfEven | Round to nearest neighbor, where an equidistant value is rounded to the nearest even neighbor. This is the default rule. |
| halfDown | Round to nearest neighbor, where an equidistant value is rounded down. |
| halfUp | Round to nearest neighbor, where an equidistant value is rounded up. |
| ceiling | Round to a more positive number. |
| floor | Round to a more negative number. |
| down | Round towards zero. |
| up | Round away from zero. |
