For rounding the number grades, do we round down all the numbers that are below the middle of two grades and round up all the numbers that are above the middle of two grades? For example, if the number grade is 3.8, should we give an "A-" or an "A"?

Yes. And 3.8 is rounded to A- as it's closer to 3.7 instead of 4.

Why do I get A- when I enter 3.85 and B- when I enter 2.85. All other numbers return correct letter grades or error message. I even tried deleting the university database.

Try changing the argument type to double.

Changing to float type solves the issue.
