Round the transcript grades?

Hi,
I'm an international and the school I'm going to apply to requires me to enter my transcript in the Courses&Grades section in Common App.

I have my official transcript. Our grading system works with grades on the scale of 100, also our transcript, intuitively. Our grades have a precision of 2 decimal digits, however, Common App only allows me to choose from whole numbers when I choose the grading scale as 1-100.

How should I round my grades? Can I round them like we learn in math classes, round up when the decimal digit after the point is equal to greater than 5, and round down when the decimal digit after the point is lower than 5.

Or should I always round down?
