To learn about the infinity symbol (∞), see wikipedia.org/wiki/Infinity_symbol and www.fileformat.info/info/unicode/char/221e/index.htm.
In HTML, there are many ways to specify ∞, including the following.
∞
∞
∞
∞
All four of the above are rendered as:
∞
In \(\LaTeX\) and \(\TeX\), the command…
\infty
…is rendered as:
\( \infty \)
And the sequence of commands…
\tiny \infty \Tiny \infty \scriptsize \infty \small \infty \normalsize \infty \infty \large \infty \Large \infty \LARGE \infty \huge \infty \Huge \infty
…is rendered as:
\( \tiny \infty \Tiny \infty \scriptsize \infty \small \infty \normalsize \infty \infty \large \infty \Large \infty \LARGE \infty \huge \infty \Huge \infty \)
To learn about these (La)TeX sizing commands, see wikibooks.org/wiki/LaTeX/Fonts#Built-in_sizes.
Since the ∞ character is not a US-ASCII character, it must be specified in a URL using Percent encoding, which is also known as URL encoding. For example, the URL of this page is:
https://www.ii.com/%E2%88%9E/
^^
NoteIn the address bar of most modern web browsers, this is displayed as:
https://www.ii.com/∞/
