[Building Sakai] Rounding Error in GB?

[Sam Ottenhoff]

50.66% looks correct to me.  The student has scored 38 points out of a 
total of 75 points.

The default behavior in the gradebook is point-based.  If an exam is 
worth 100 points and a quiz is worth 10 points, the student's score on 
the exam will be weighted 10x.  The scores of the exam and quiz will not 
be averaged.
