Is there a way to type the repeating decimal sign on top of a number on the Mathematics Stack Exchange site? I have a question I want to ask about a repeating decimal and I want to improve the cosmetic aspect of the question. Thanks in advance.

As mentioned in comments, \overline is the way to go: to get $0.5\overline{332}$, type $0.5\overline{332}$.

  • $\begingroup$ Um, no. You do. (Let me edit that...) $\endgroup$
