## Syntax in Atlassian Wiki fields

### Inline LaTeX content

To insert LaTeX content into Atlassian Wiki editors such as Description or Comment in inline mode:

* Select the **Text** mode (you must make sure ithe editor is not in **Visual** mode.
* Wrap the content inside the `{latex-inline}...{latex-inline}` macro.
* You can go back to **Visual** mode to type other content after that.

```
{latex-inline}e = mc^2{latex-inline}
```

### Block LaTeX content

To insert LaTeX content into Atlassian Wiki editors such as Description or Comment in block mode:

* Select the **Text** mode (you must make sure ithe editor is not in **Visual** mode.
* Wrap the content inside the `{latex-block}...{latex-block}` macro.
* You can go back to **Visual** mode to type other content after that.

### Complex LaTeX content

Sometimes the symbols in complex LaTeX content can be misinterpreted by Atlassian Wiki as formatting syntax. To type such complex LaTeX content:

* You can go back to **Visual** mode to type other content after that.
* Wrap the content inside the `{noformat}//[...//]{noformat}` macro.
* Select the **Text** mode (you must make sure ithe editor is not in **Visual** mode.

```
{noformat}//[
\begin{align*}
a^2 + b^2 &= c^2, \\
e^{i\pi} + 1 &= 0, \\
\int_0^\infty e^{-x} \, dx &= 1.
\end{align*}
//]{noformat}
```
