Mistake in Supplemental Application of CSULB For 2015 Fall?

I applied Cal state long beach for fall 2105. As, I am a transfer student, they made me do a supplemental application where I had to report my gpa including my fall gpa. I did a mistake calculating my gpa as I counted 3 unit class as 4 unit which resulted my gpa to be 3.19 but I caught my mistake today and the gpa became 3.18. I also checked my application status online and they have offered me admission. Now, I am really scared that they might withdraw the admission decision because of that mistake. They might think I lied. So I am very scared as long beach is my first choice of school and I made such a dumb mistake. I just need somebody familiar with the matter answer the question?

It probably be best to be up front with them about it and call them. They might understand. .01 off is not too much honestly…
