There are Unicode characters for a few fractions, such as ½. This looks a little better than 1/2, depending on the context.

Here’s the Taylor series for log(1 + *x*) written in pure HTML:

log(1 + *x*) = *x* – ½*x*² + ⅓*x*³ – ¼*x*⁴ + ⅕*x*⁵ – ⋯

See this post for how the exponents were made.

Notice that the three dots ⋯ on the end are centered vertically, like `\cdots`

in LaTeX. This was done with `⋯`

(U+22EF).

## Available fractions

The selection of available fraction number forms is small and a little strange.

There are characters for fractions with denominator *d* equal to 2, 3, 4, 5, 6, and 8, with numerators 1 through *d*-1, except for fractions that can be reduced.

If *d* = 7, 9, or 10, there’s a character for 1/*d* but not for fractions with numerators other than 1. For example, there is a character for ⅐ but not for 2/7.

## HTML Entities

For denominators 2, 3, 4, 5, 6, and 8 the HTML entity for characters is easy: they all have the form

`& frac <`

*n*> <*d*> ;

where *n* is the numerator and *d* is the denominator. For example, `⅗`

is the HTML entity for ⅗.

There are no HTML entities for 1/7, 1/9, or 1/10.
