Learn@UW/D2L - Constants pi and e Must be in Lower Case in Formula Calculation Questions
The constants pi and e must be in lower case in the formula in Arithmetic and Significant Figures questions that may be used in quizzes.
If you test a formula containing PI or E using the "Test" button, the symptom is the message
"Error: Input string was not in a correct format."
Existing quiz questions using upper case PI or E in the formula may not be properly scored. You should edit such questions changing PI to pi and E to e.
In previous versions of the Learn@UW application, upper case PI and E were allowed.
This is a known issue.
