Even in the 'Error if grade not listed case', it was applying a small
tolerance. In the case of a fuzzy match, it was returning the inexact
grade from the import file, rather than the precise grade that Moodle
was expecting.
That causes problems when the editing form is displayed, because the
value from the database does not match any of the available options, so
the grade is changed to 0%.
NUMBER(X,Y) typically come back from the DB as strings. If you don't
convert them to float, then when you display them, it appears as
1.0000000, which is not normally what you want.
Also, increase the size of the field on the edit form, so if you
question does have default mark 0.1234567, you can see that!
I don't believe this will actually fix the reported problem, which I
cannot reproduce, but it should give us much better error messages, at
which point we can fix it.
New keep roles/enrolments and groups/groupings options, notification CSS fixed, standardised notification texts, added missing delete of module blocks, fixed file deleting and some other minor issues.
1. We need this so that, for example, when previewing a question from
the quiz editing page, the preview uses the filter settings, theme and
language set for that quiz and course.
