I know of a certian ISO standard that says "don't italicize constants" but it isn't in widespread use. So should $\pi$ be in italics or not? What's more common in actual usage?
Feel free to tell me how to improve, this being my first question here.

The second last paragraph says that in some style guidelines, it should be italicized, and in others it shouldn't. So the final answer is: It depends on who is editing your paper.
