| get_matching_answer($value, $multiplier) X-Ref |
| Get an answer that contains the feedback and fraction that should be awarded for this response. param: number $value the numerical value of a response. param: number $multiplier for the unit the student gave, if any. When no return: question_answer the matching answer. |
| is_unit_right(qtype_numerical_answer $answer, float $value, ?float $multiplier) X-Ref |
| Checks if the provided $multiplier is appropriate for the unit of the given $value, ensuring that multiplying $value by the $multiplier yields the expected $answer. param: qtype_numerical_answer $answer The expected result when multiplying $value by the appropriate $multiplier. param: float $value The provided value param: float|null $multiplier The multiplier value for the unit of $value. return: bool Returns true if the $multiplier is correct for the unit of $value, false otherwise. |
