Understanding iLearn rounding rules

When rounding, iLearn Learning Environment automatically applies the Round to Half Even rounding rule when assessing answers that contain decimal places that end with "5". Currently, there are no options to change rounding rules. Applying the Round to Half Even rule, answers with decimal places that end with "5" will round down instead of round up.

Example One: 3.41 * 25 = 85.25

If you create an arithmetic question and set the Answer Precision to 1, the correct answer using Round to Half Even is 85.2.

Example Two: -3.41* 25 = -85.25

If you create an arithmetic question and set the Answer Precision to 1, the correct answer using Round to Half Even is -85.2.

You can enter a unit type (mm, cm, grams, inches, etc.) to assess if answers include correct units of measurement. For significant figures questions, you can select a percentage to assign a weighted points value to the measurement unit. If you use units in your question, you can set the following Evaluation Options:

• Case Insensitive - Auto-grading searches for a matching character pattern in the answer text with or without letter case correctness.
• Case Sensitive - Auto-grading searches for a matching character pattern in the answer text that must have letter case correctness.
• Regular Expression - Auto-grading uses meta-characters to search for one or more matching strings in the answer text's character pattern. What you set as meta-character parameters helps determine letter case sensitivity.
