Rounding to the nearest 100

Hi there,

I have an arithmetic question in BrightSpace where students are required to round to the nearest hundred.

Round {a} to the nearest hundred.

I was just wondering what the formula should be for this question for it to work correctly. At the moment, the formula is round({a}), but all the answers are coming up as 0. Any advise on this would be greatly appreciated.

Thank you

    Hello @Joseph.C.99, it seems there isn’t any existing documentation addressing your specific question. I’d recommend raising a ticket with the D2L Support Team through your institution's helpdesk for further assistance. Please let me know if you need any help with that!

    From the Brightspace Question Editor documentation for the arithmetic question type (https://community.d2l.com/brightspace/kb/articles/2800-creating-question-library-questions#create-arithmetic-questions) the listed mathematical functions doesn't include a round({a}) function. You can also find the list of supported functions by selecting the ? button to the right of the formula field in the question builder.

    In some situations you might be able to use the modulo operator as a work-around, but it would only work in situations where you know that the value must be rounded up, or must be rounded down.

    For example, if you defined a to have a minimum of 100 and a maximum of 149, you would always be rounding down to 100 in that case. Then you can use the formula {a}-({a}%100).

    Alternatively, if the variable was restricted to 250 to 299 you know that you are always rounding up to 300 in that instance, so you could use this formula {a}+(100-({a}%100)).

    It wouldn't be a bad idea to request a round({a}) function through the Brightspace Product Idea Exchange (PIE) or upvote it if someone has already requested it.

    Thank you so much @Ron.W.451 and @Krizzy.S.9720. Both answers are very helpful. How do I raise a ticket with the D2L support team for this issue?

    Hello @Joseph.C.99!

    You may need to reach out your institution's administrator (internally) so that they could help you raise a ticket! I will inbox you for more information.

    Simultaneously, we feel that this is a very good idea so you can also request a round({a}) function through the Brightspace Product Idea Exchange (PIE). This is a helpful link to get started!
