I have to write x/100000 with square character: x*10-5 ,but the '-5' should be above 10 so it is known that it is x/10/10/10/10/10.

How do I do that?

If you are trying to get x*10-5, as you would write it by hand, then your only option is your word processor's superscript option for text (unless you have a full equation editor feature handy).

The only superscript characters I know of in Unicode are 1, 2, 3 (listed as sup1, sup2 and sup3 respectively in this reference) and those characters that are naturally above the centre-line (such as the degree symbol).

The common way of representing such a math clause in plain text is x*10^-5 (this is how it would be represented in most programming languages).

I use ctrl+shift+= in ms word. :) – John Jun 1 '10 at 17:42

Assuming you mean in a word processor of some sort, you probably want to format the '-5' as superscript.

Also, if it's '-5', then is isn't a square character. It's only squaring when it's raised to the power of two.

Exactly what I needed. The 'superscript' and 'subscript'. Thank you! :) – John Jun 1 '10 at 17:41

You can copy-paste superscript numbers (and minus sign) from here: ⁻ ⁰ ¹ ² ³ ⁴ ⁵ ⁶ ⁷ ⁸ ⁹

These can also be helpful: ½ ⅓ ⅔ ⅕ ⅖ ⅗ ¼ ¾ ⅘ ⅙ ⅚ ⅛ ⅜ ⅝ ⅞

Great idea to make them available for copying, thanks! Weirdly, the 123 are not the same height as the rest of the numbers… – w00t May 16 at 10:30
@w00t Depends on the font you use. Try it on the surface you wish to use it to see if it is visible there. – mg30rg May 17 at 7:51

The most common superscripts of 1, 2 and 3 were included in ISO-8859-1, but a full superscript number set is available in Unicode.

U+2075 is ⁵.

Details are available from, which is authoritative.

More information is also at Wikipedia.

If you are on a Mac, type Ctrl+Cmd+Space and you will get an Emoji popup. Then, type the number you want (2) and the square will be part of the results 😎
