    Description

      When creating a quizz, only use cloze sub-question with 0 as a grade.

      In /question/type/multianswer/question.php, you get a division by zero in get_max_fraction().

      Then when starting the quizz, you get a database error :

      Default exception handler: Error writing to database Debug: Unknown column 'NAN' in 'field list'\nINSERT INTO mdl_question_attempts[...]

       

      It only happens with PHP 7.
