Also confirmed in the mysql instance on sakai-stable.
T&Q assignments displayed in the Gradebook don't have fractional scores rounded up or truncated, even though they are rounded up to the nearest tenth of a point in the T&Q tool. (see screenshot)
Steps to verify:
1) Create and publish an assessment (make sure the "send scores to gradebook" option is on.)
2) Take it as a student, submit for grading.
3) View the submission score in T&Q. Change the total score to a number with trailing decimal places (15.321, for example), and click Update. The score is adjusted to 15.3.
4) Now view the assignment score in Gradebook. There, the submission score is given as 15.3000001907349.
