[Building Sakai] [samigo-team] Loss of precision when instructor exports the assessment's results

[Sanghyun Jeon]

We plan to use Sakai 2.9.3 Next semester. During our test, we find out that
Sakai 2.9.3 still has the described issue of SAM 1562. Would you mind
confirming this?
Thank you in advance.
