# Repeating decimal sign

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.

• $4.\overline{285714}$? $4.\overline{285714}$ – Daniel Fischer Jan 8 '15 at 3:36

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