Suppose I have a student with a final percentage grade of 89.7%. My gradebook is set up so that this would be a B+, and if I switch the view to letter grade it really does show up as a B+. So far so good. But let's say that I want to round all the final grades to the nearest percent. I go into Settings and change the number of decimal places for rounding to 0 instead of 1. If I now switch the view to letter grade instead of percent, this student does indeed show up as 90%. However, the letter grade is still a B+ instead of an A-.
Is there any way to have the gradebook change the final letter grade in response to the rounding operation?
