In assignment grading when using marking workflow and rubric, the grades are displayed as integers.
Before MDL-69867 they were displayed with decimals.

Attached are screenshots of the grade in view submissions (mod/assign/view.php?id=xxx&action=grading), and marking workflow before and after MDL-69867 (mod/assign/view.php?id=xxx&action=grader&userid=xxx)

Example:
The student got a grade on 3.5 from 5. This is displayed in "View all submissions" as "3.50 / 5.00".

Expected result:
"Current grade in assignment" should display the grade as decimal. The grade was displayed as "3.5" before MDL-69867.

Actual result:
"Current grade in assignment" displays the grade as "3 / 5" (integer, not decimal).
