[LON-CAPA-users] submission masaging
Thu, 17 Jul 2008 14:35:58 -0400
What kind of massaging does LONCAPA do
to the string of text that is entered
for an answer?
I ran into a situation where a student entered
the number 1.1e-7 as 1.1 e-7. LONCAPA took out
the spaces before it checked the answer and then
marked the problem correct. I then grabbed the
submission (via &EXT) and assigned it to a variable
and then used the variable in a calculation, without
removing spaces (who would have thought...) and got
an answer I didn't expect. Interestingly, LONCAPA
used the mantissa (the 1.1 part) in the calculation and
ignored the rest of the submission.
So, I guess I need to massage the submission
the same way LONCAPA does in order to avoid
this situation in the future.
