I am applying for a master’s program in the US and am not sure how I should present my GPA ethically when discussing it. I have an undergrad total GPA of 3.394 and when asked to put in my undergrad GPA it only gives room for 2 digits and nothing more. EX: 3.0. Can I round up my GPA since it’s so close to 3.4, or would this be unethical and I should round down to 3.3?

To make this as general as possible: How should one round their GPA when only 2 digits are accepted, and they’re less than .05 away from the next digit?
