[answered]Square root symbol

√

There ya go.

Future reference - Start/Programs/Accessories/Character Map. This will give you all the characters available to you, and you can copy them to the clipboard.

√

..Delete '+' from the following: "&#+8730;"
and try posting the rest without a space.

Where do you get &#+8730 from? I never posted that. It was a straight copy from the character map program.

It is the Unicode for the square root symbol.
Try deleting '+' from &#+8730; (do not omit the character ';' at the end.)

Oh, I get it. It's like using Chr() to get a character in VB.

Nope. . .like I said, I just did a straight cut and paste from the character map utility that comes with windows.

I know about the character map, but the unicode is universally applicable in any platform and displayable if the browser is able to use appropriate fonts without any consideration of charsets.

I dunno... both samples look like boxes to me.

When in doubt SQRT() or ()^(1/2)

It's a pretty wishy washy little object, but if thats it thanks all.

still looks like a box here.

A box? It looks like a tick to me, it isn't what I remember the square root symbol looked like at school though.

I would just use the abbreviation 'sqrt' as in

sqrt(4) = 2

you could alternatively use
4 ^(1/2) or 4 ^ (.5)

As you can see, any symbol is going to cause problems with a large number of readers.

Alternatively you could create a gif of the problem.

I had a play about, this was the nearest I came. \/¯9

That works...

The box I spoke of earlier is what happens with a character that cannot be displayed (machine dependant...)

Still looking for limericks?

(machine dependant...)

No, it's font dependent.

.

note: the symbol √ denotes "the positive square root of" what is under the symbol.

There is also a "negative square root", denoted -√

By the way, I'm on a different machine, and I can see it now...

If the font is on different machines, but it's the same font...

Are you sure it was the same font?

To type a character using unicode requires a separate number pad, as on a full-size keyboard, something most laptops lack. As mentioned earlier, Character Map is handier than remembering the keypress strings anyway, and copying from it is about the only way to get special characters using a laptop. It can be accessed via "Accessories", or from the Start > Run, by typing "charmap" (without the quotes) into the dialog box and clicking "OK" ... up pops Character Map. The version available in XP has lots of features, including a sort-by--subset, which is handy, but even the version in Win95 is workable. If there are a few characters you want to use frequently, copy-and-paste them into a Notepad or Wordpad document, and "Save As" "Special Characters", or something that makes sense to you, and store it in "My Documents" or on your desktop, or where ever is convenient. Then, when you want a special character, just open that saved document, copy the character, and paste it into your new document. Oh, and while lots of fonts are available, if you stick with Arial or Arial Black, just about any Browser/OS/Machine combo will be able to see it.
