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.
