How it works

The repeating symbol is a bar over the digits that repeat: 0.3̅ is 0.333 without end. Unicode has no barred digits, so each one here is a digit followed by U+0305, Combining overline, which Unicode also calls vinculum.

Read the full guide

Any digit, any length

Type the digit, then paste the bare bar after it. For a group that repeats, paste the bar after each digit: 0.1̅4̅2̅8̅5̅7̅ is one seventh.

Bar, dots or parentheses

The bar is the convention in the United States and Canada, among other countries. The United Kingdom and Australia put a dot over the first and last repeating digit, and parts of Europe put the group in parentheses: 0.(3) is the same number as 0.3̅. No notation is used everywhere.

0.9̅ is not almost 1. It is 1, written another way.
The spacing overline ‾ and the macron ¯ take their own space and do not move over a digit.
Whether neighboring bars join into one line, and how neatly each sits over its digit, depends on the font.

Questions and answers

How do I type the bar over a repeating decimal?

Type the digit, then add U+0305, Combining overline. It has no key or HTML name and is in neither Alt code table, so the quick way is to paste the bare bar after the digit. In a web page, ̅ writes it.

What is the vinculum symbol?

A horizontal line drawn over part of an expression. Its common job today is to mark the digits of a decimal that repeat, and it is also the bar over what stands under a root. In Unicode the combining overline, U+0305, carries the name.

What does a line over a number mean?

Over digits after a decimal point it means those digits repeat without end: 0.6̅ is 0.666 and so on, which is two thirds. The digits that repeat are called the repetend.

Is there another symbol for repeat?

Yes, for other kinds of repeat. 〃 is the ditto mark, 々 is an iteration mark of East Asian writing, 𝄆 and 𝄇 fence a repeated passage of music, and 🔁 is the repeat button. Each has a row in the table.

How this list was compiled: Names, and the code points they belong to, are checked against UnicodeData.txt, version 18.0.0 (https://www.unicode.org/Public/18.0.0/ucd/UnicodeData.txt), and printed in sentence case. Notes that begin Unicode's note quote NamesList.txt of the same version (https://www.unicode.org/Public/18.0.0/ucd/NamesList.txt); the version a character was added in is from DerivedAge.txt (https://www.unicode.org/Public/18.0.0/ucd/DerivedAge.txt), block names are from Blocks.txt, and the years are from https://www.unicode.org/history/publicationdates.html. Unicode has no single character for a digit under a bar, so those rows are a digit followed by one combining mark, U+0305 or U+0307; the notes give both code points. HTML entity names are from https://html.spec.whatwg.org/entities.json, the Alt code from https://www.unicode.org/Public/MAPPINGS/VENDORS/MICSFT/WINDOWS/CP1252.TXT and the Option key from CLDR's record of the U.S. layout (https://github.com/unicode-org/cldr/blob/release-42/keyboards/osx/en-t-k0-osx.xml).
