# Oxidation number approximately

I argued with my lecturer when he is saying that during the calculation of oxidation number, and your answer give you like 3.46 you can approximate it to whole number, I know tell him NO that if the answer is in decimal that means your calculations is wrong, he now tell me to go and research on my thought.

So please can anyone help me out

Oxidation numbers of particular atoms are integer numbers, with exceptions when extra electrons ( or theirs deficit ) are shared among different number of atoms. The particular example of this are superoxides $$\ce{M^{I}O2}$$.
