Attention

Version 4 is now the current version of MathJax. This document is for version 3.2.

centernot

The centernot extension implements the centernot style package from LaTeX. It provides the \centernot command which can be used as a replacement of the standard \not command and generally leads to a better alignment of the slash with the operator it negates. This can be observed with the following two examples:

\begin{array}{c}
  A \not\longrightarrow B\\
  A \centernot\longrightarrow B
\end{array}

\begin{array}{c}
  A \nparallel B\\
  A \not\parallel B\\
  A \centernot\parallel B
\end{array}

See also the CTAN page for more information and documentation of centernot.

In addition to \centernot the package also implements the non-standard \centerOver.

\centerOver{symbol1}{symbol2}

Overlays symbol2 centered on top of symbol1.

This package is not autoloaded, so you must request it explicitly if you want to use it. To load the centernot extension, add '[tex]/centernot' to the load array of the loader block of your MathJax configuration, and add 'centernot' to the packages array of the tex block.

window.MathJax = {
  loader: {load: ['[tex]/centernot']},
  tex: {packages: {'[+]': ['centernot']}}
};

You can configure the autoload extension to load centernot via

window.MathJax = {
  tex: {
    autoload: {
      centernot: ['centernot', 'centerOver']
    }
  }
};

Alternatively, use \require{centernot} in a TeX expression to load it dynamically from within the math on the page, if the require extension is loaded.
