Course completion "grade" criteria assume all grades are percentages

1. Create a course and add 2 assignments each with a grade of 80.
2. Visit <yoursite>/admin/settings.php?section=optionalsubsystems and enable completion tracking.
3. Visit the course settings and set 'Completion tracking' to 'Enabled, control via completion and activity settings".
4. Click on 'Course completion' in the 'Course administration' menu and check to enable the course grade and set it to 80.
5. Add the 'Course completion status' block.
6. Log in as a student and submit to each assignment.
7. As an administrator give each submission a 38/80.
8. Log back in as a student.
9. Completion block should show that course is not completed and the grade is 76, and 80 is required (no '%' sign)
10. Completion report should also not mention any %
11. Login as teacher and view completion report (make sure there are no %)
12. Click on student name and, again, make sure there are no %

Also three other things fixed:
Error 1 - extra rounding in the form:

1. Create a course
2. Go to course completion and add a grade condition with minimum grade 75.99
3. Save form and open it again
4. In the grade condition you should see 75.99000 (before fix you'd see 76.0)

Error 2 - incorrect rounding in the report (always 2 digits):

1. Create a course
2. Go to grades settings and set "Overall decimal points" to 3
3. Go to course completion and add a grade condition 75.111
4. Make sure course completion report displays 75.111 (and not 75.11 as before fix)
5. Change setting to 1 or 0 decimal points, this should be respected in both course completion block and report

Error 3 - number format

1. switch to language with different decimal separator (French, Russian, etc)
2. In the previous test make sure that the grade is displayed with a language-specific decimal separator (i.e. comma)
