KaTeX Tests

This page is copied from https://katex.org/docs/support_table.html for testing rendering $\KaTeX$ in DoIt.

This is a list of TeX functions, sorted alphabetically. This list includes functions that KaTeX supports and some that it doesn’t support. There is a similar page, with functions sorted by type.

If you know the shape of a character, but not its name, Detexify can help.

$$\text{This is looooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooong.}$$

$$ \text{This is short.} $$

Math shortcode test: $\|\boldsymbol{x}\|_{0}=\sqrt[0]{\sum_{i} x_{i}^{0}}$

$$\|\boldsymbol{x}\|_{0}=\sqrt[0]{\sum_{i} x_{i}^{0}}$$
