Default

This is a non-editable field, but a tick will display for the Rounding Rule that has been flagged as the default rule. 

See the section on 'Set Default'.

Default Rounding Rule

A System Default rounding rule is automatically present in your system. It uses the 'Round 0.5 Up' rule, that is, decimals numbers ending in 1-4 are rounded down, while decimal numbers ending in 5-9 are rounded up.

The default rounding rule is automatically applied to every Final Results and Overall Subject Grades objective's calculation rule in your Markbook, unless and until it is changed to an alternate rounding rule.

You can modify the System Default rounding rule, or add an alternate rule and flag it as the default rule.

Set Default: Once the Rounding Rule that you wish to set as the default rule as been added, select the 'Set Default' button and choose the Rounding Rule from the picklist.

View / Edit / Delete Rounding Rules

View: View the Rounding Rule in non-edit mode.

Edit: Open the Rounding Rule in edit mode. The Code cannot be changed.

Delete: Rounding Rules can be deleted where they have not been used in a calculation.

Rounding Rules cannot be deleted if they have been used in calculations, but they can be made inactive if they are no loner needed.

Change an objective's Rounding Rule to a non-default Rounding Rule

  • In Markbook, navigate to a reporting period and a subject.

  • From the hamburger menu for a Final Results or Overall Subject Grades objective, open the 'Calculation Rules' screen.

  • Select the preferred Rounding Rule from the picklist under the 'Rounding Rule' column for the objective.
