<p>From the student perspective, a numerical question looks just
|
|
|
|
|
like a short-answer question.</P>

<p>The difference is that numerical answers are allowed
|
|
|
|
|
to have an accepted error. This allows a continuous range of answers
|
|
|
|
|
to be set.</P>
|
|
|
|
|
|
|
|
|
|
<p>For example, if the answer is 30 with an accepted error of 5,
|
|
|
|
|
then any number between 25 and 35 will be accepted as correct.</p>
|
|
|
|
|
|
|
|
|
|
<p>Numerical questions can also have case-insensitive non-numerical answers.
|
|
|
|
|
This is useful whenever the answer for a numerical question
|
|
|
|
|
is something like N/A, +inf, -inf, NaN etc</p>
