Calculations changed from using BigDecimal to BigFraction – 3900.89

Blackboard Learn SaaS and Learn 9.1 
Ultra Experience and Original Experience 
Ultra Course View and Original Course View 
Impact: Instructors, Students

Instructors need a gradebook that supports diverse grading scenarios. We are changing the software library used to perform calculations in calculated columns and the overall course grade.

Example: A course contains 3 assignments worth 22 points each. The student scores 13/22 on the first assignment, 14/22 on the second assignment, and 15/22 on the third assignment. An instructor creates a calculated column to calculate the average of these assignments.  

Using the new software library, BigFraction, the average will calculate as 14/22.

With the former software library, BigDecimal, the average would incorrectly calculate to 13.99/22. The new software library ensures calculations compute as expected.

For administrators: This change applies to both Ultra and Original courses. There are no configurations needed.
