Make storage and display of assessment scores consistent

Description

1: Scores should be stored and transmitted between tools (as opposed
to displayed) with the highest possible accuracy (i.e. doubles).

2: The default display of scores should be 2 decimal places. For
example, 1 out of 3 is displayed as ".33"

Assignments, Tests & Quizzes (Samigo), and Gradebook currently store
and display point-based assessment values in different maners. A
recent discussion in the email thread in sakai-
assessment@collab.sakaiproject.org called "Consistant grading
()" illustrated why this is a problem and had the above
consensus.

----------------------------- Original Description:
Assignments, Tests & Quizzes (Samigo), and Gradebook currently store and display point-based assessment values in different maners. The recent discussion in the email thread in the "Sakai DG: Assessment Tools" illustrates why this is important and suggests appropriate resolutions. Exisiting assessment tools and any new related tools should conform as best as possible to a standard approach to point-based storage and display.

In particular, the developing consensus for storing point-based assessments values appears to be doubles. By storing with as much percision as possible, then round-off errors are less likely to generate confusion for students and instructors.

For the display of points, the developing consensus is for two decimal places. This will help also help reduce confusion related to round-off errors. For example, 0.33 or 0.67 perhaps more clearly indicate you received one-third or two-thirds of a point, respectively, on an assessment item. A desire for configuring the number of decimal places, at the system-wide and/or site-wide levels, has also been expressed; as has the desire not to allow such configuration.
