Description
When using a calculated formula, the “Logarithm to base n” does not calculate, and the question cannot be created using the formula.
Steps to Replicate
Log in to Blackboard Learn Ultra Experience as an Administrator
Create a new Ultra Course.
Create a test
Create a calculated formula.
In “*Question Text” you can use [x]
In “*Enter the answer formula” Go to the calculus tab (alt+9 in windows)
Select “Logarithm to base n” -> set log2(x) and hit next
In “Rounding” Decimal places = 3 (you can set it with no decimals but the answers are more understandable with decimals)
In “Variable ranges” MINIMUM=1 MAXIMUM=5 DECIMAL PLACES =0 Number of answer sets = 5 and hit next
Observed Behavior:
In verification step, each answer shows “Unable to calculate row”
Expected Behavior:
Answers should appear:
log2(1) = 0
log2(2) = 1
log2(3) = 1.585
log2(4) = 2
log2(5) = 2.322
