dsfont

The dsfont extension implements the dsfont style package from LaTeX. See the dsfont CTAN page <https://www.ctan.org/pkg/dsfont>__ for more information and documentation.

This extension defines the following commands:

.. describe:: \mathds{math}

Typesets math using the dsfont blackboard-bold fonts.

The dsfonts come in two forms: serifed and san-serif; which one is used is determined by an option described :refbelow <tex-dsfont-options>.

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

.. code-block:: javascript

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

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

.. _tex-dsfont-options:

dsfont Options

Adding the dsfont extension to the :data:packages array defines an :data:dsfont sub-block of the :data:tex configuration block with the following values:

.. code-block:: javascript

MathJax = { tex: { dsfont: { sans: false } } };

.. _tex-dsfont-sans: .. describe:: sans: false

Determines whether the sans-serif font is used rather than the serifed version.

.. _tex-dsfont-commands:

dsfont Commands

The dsfont extension implements the following macros: \mathds
