[Building Sakai] Rounding Error in GB?

[David Horwitz]

Hi All,

One of our users reported an issue with course grade calculations in
gradebook that I've reported as:

http://jira.sakaiproject.org/browse/SAK-19377

It looks like a rounding/precision error - which I recall there where
some complexities with but which the details escape me. The case is this:

1) Create items marked out of 20, 28 & 27 points
2) give a student 11/20, 11/28 & 16/27

The resulting course grade according to sakai is 50.66% rather than the
expected on of 51.18%


So far I have not found the place in GB where this calculation is done
so haven't found solution....
