Hello all,
Is there an easy way to access just the numeric portion of a student's
submitted answer?
In other words, if a student submits 54.6 m/s as an answer, is there a way to
strip the non-numeric characters to use just the 54.6 as a point on a gnuplot,
for example?
So my script would include:
$vi_submitted=&EXT('user.resource.resource.15.16.submission');
but then what?
Thanks!
