Writing the GPA in the application form, even though the studies have not finished yet

In the application form of the master's program that I'm applying for, I'm obligated to write my GPA, and I cannot leave it blank, as the form cannot be submitted in that case. I still have one more semester to complete my Bachelor's degree studies.

What do you suggest to write in the field? Should I simply write my GPA, or should I add any phrases afterwards such as: 4.9 out of 5 (5 semesters)
