Is there a Unicode character for plus over minus? (+/-)

Solution 1

This is the only one I have seen in unicode (plus over minus):

±

HTML/XML Character reference:

&#177;

HTML Named Entity:

&plusmn;

This symbol is used to indicate the precision of an approximation.

Solution 2

You can approximate it to some extent with a superscript plus (U+207A), a division slash (U+2215) and a subscript minus (U+208B):

⁺∕₋

However, it requires font support to get right. Especially the super- and subscript +/− are not available in most fonts, so it might just render horribly.

For reference, that's how it looks for me (better than five years ago, but still somewhat broken):

However, using Cambria Math in Word 2010 it looks like this:

Which probably is exactly how it should look like (follows the same typesetting rules as fractions).

Solution 3

You mean like ± (U+00B1 / "\x00b1")?

Edit: speaking specifically to a design which uses a solidus, the best I could find was ⁺⁄₋ which is U+207a (superscript plus sign) U+2044 (fraction slash) U+208b (subscript minus). The fraction slash has negative kerning in some fonts, which causes the appearance of composition. See this JSFiddle for an example of how this works with a larger font size.

<div style="font-size:20em;">&#x207a;&#x2044;&#x208b;</div>

Solution 4

⁺⁄₋

<sup>+</sup>⁄<sub>−</sub>

Occasionally I've seen the symbol "plus or minus" written in fractional form, like this:

Is there a Unicode character for this?

Note: I already know about the standard "plus-minus sign" symbol, but it won't work in this context. I'm specifically looking for a version with the fraction bar.

  Yes. ± fileformat.info/info/unicode/char/b1/index.htm

  This question appears to be off-topic because it is about finding a Unicode character.

  Matt: That's assuming that there is a single character for that and that there are no other means of getting that glyph. That assumption may not be valid and I doubt a search engine might turn up my solution.

  This seems to me like an alternative glyph for ±, in which case the question would be “is there a font that renders ± with a slash”?

Looks better for me than for you ;-)

⁺∕₋ is definitely the way to go. HTML: ⁺∕₋ links: fileformat.info/info/unicode/char/207a/index.htm fileformat.info/info/unicode/char/2215/index.htm fileformat.info/info/unicode/char/208b/index.htm

Works great. Swift: let plusMinus = "\u{207A}\u{2215}\u{208B}" renders nice with the default font in aUILabel.
