Infinity Sign in HTML?

[NanoByte]

OK, how do I print an infinity sign on this board, which symbol is supposed to be encoded by &inf; or ∞ or ƥ ?

Your best bet is to find an image on the infinity sign and use that.

Those types of characters probably won't show up in older browsers.

[NanoByte]

What are "those types of characters"?

IIRC, the Infinity character was introduced in the HTML 4.0 specification. As we all well know, the two major browsers, Netscape and Internet Explorer don't support HTML 4.0 completely! IE 5 comes closest, followed be IE4 and then Netscape 4.

Here is a test of extended HTML characters.
<hr>
&cent; £ &copy; Æ &oslash;

&infin; ∞ &spades; &piv; %#8240
<hr>
You should see the following characters:
cent (twice), Copyright, "AE", an o with a slash;

infinity (twice), a spade, pi, and 0/00

The cent and copyright should work with most browsers.

Some browsers use a "?" in place of the codes it couldn't understand, others will probably leave it blank, or display the code itself.

Same as above, except using all number format.

Sorry, Tuba and Nano; this is taking longer than I thought.

Anyway, using the two browsers I have on my system here are the results.

IE 4 displayed all of the characters except the spade and the pi symbols.

Netscape 4.7 couldn't display the pi, the spade or the infinities. So krish's suggestion would be best.

In each of your examples, my browser (IE 4.0 on Win95) showed

on the first line in each case:

cent, British-pound-sterling, copyright, capital ash, slashed "O" .

The second line showed

Ex 1: infinity, infinity, square, square, "%#8240" (stuff in quotes were run together, as shown)

Ex 2: infinity, infinity, square, square, 0/00 as a single character

Ex 3: infinity, infinity, square, "&982;", 0/00 as a single character

You should probably ignore the times a number showed up. That's when I f*cked up the code.

New Test to determine if your browser supports mnemonic coding or numeric coding.

Line1
(C), (R), cent, AE, uppercase thorn,

Line2
Delta, [lowercase] pi, [uppercase] sigma, infinity, Club


Test #1 Mnemonic<hr>
&copy; &reg; &cent; &AElig; &THORN;
&Delta; &pi; &Sigma; &infin; &clubs; <hr>

Test #2 Numeric<hr>
© ® ¢ Æ ß
Δ π Σ ∞ ♣ <hr>

Hope it works.

SN, I think you goofed on cap thorn; it's #222, not #223, which is German sharp 's'. [see my prior post here]

Thanks, I misread my HTML book.

IE 5.0 showed the spade as well, in all trials.
