How do I add a dot or line above a number in Word to indicate a repeating decimal?

10 Aug

This is something that is used when working with maths texts – a friend who is studying maths asked me about it a while ago. This article will show you how to add a dot or line over a number in a Word document to indicate a repeating decimal.

Type your number first, then go to the Insert tab and look for the Symbol section to the right:

1 insert symbol

Click on the little down arrow below Symbol

 2 insert symbol

Choose More symbols

 3 more symbols

Drop down Subset and find Combining Diacritical Marks

 4 subsets

Scroll down a little and you will find the dot and various lengths of line:

5 combining diacritics

Highlight the symbol you want to use and click Insert to insert the dot:

6 combining diacritics

Note that this will look different according to which font you’re using.

When you want to do this again, you only need to click on the down arrow under Symbol and you will find recently used symbols showing in the first drop-down:

7 combining diacritics

This article has explained how to add a dot or line over a numeral to indicate a repeating decimal.

    This was easier than I thought it would be! Occasionally I have to use the Insert button, but always for diacritical marks in text. Never thought of perusing the entire list there. Thank you!

    my problem is how to place a vinculum over a decimal part. for ex: 0.3 is the number. I need a overline/ vinculum/ line segment over the digit 3 only.

      Have you tried this and did it not work? If you can give me more info, eg. version of Word, PC or Mac, I can see if I can find an answer.

    Hello, I am Anthony from Tennessee, finishing editing my first book, finally paid for. I’d like to put a vinniculum “over” as in “on top of” a set of two #’s. Not behind or in front, which seems to be all I can do. It would help my final edit if you could help~! Thanks and God Bless.- Anthony.

      Thanks for your question, Anthony. Does there need to be a line over each # or one bridging the two of them?
