<tmdoc-title|Mathematical environments>
The <tmdtd|env-math> <abbr|d.t.d.> specifies which mathematical
environments can be used inside text-mode. In other words, the environments
should be used inside text-mode, but their bodies contain mathematical
formulas or tables of mathematical formulas.
<\explain|<explain-macro|equation|body>>
A numbered equation.
</explain>
<\explain|<explain-macro|equation*|body>>
An unnumbered equation.
</explain>
<\explain|<explain-macro|eqnarray|table>>
An array of numbered equations (not yet implemented).
</explain>
<\explain|<explain-macro|eqnarray*|table>>
An array of unnumbered equations.
</explain>
Inside the <markup|eqnarray*> environment, you can use the
<markup|eq-number> tag in order to number the equation.\
<\warning>
The numbering of equations inside tables is not yet as it should be. In
particular, the <markup|eqnarray> tag is equivalent to <markup|eqnarray*>
at the moment. Later on, when the <markup|eqnarray> tag will be
implemented correctly, you will also have a <markup|no-number> tag in
order to suppress the number of an equation, and a style package for
numbering equations at the left hand side.
</warning>
<\warning>
There is no option for numbering equations at the left hand side
available yet. Nevertheless, you may use the manual tag
<markup|leq-number> for this. You also have a tag <markup|next-number>
which directly display the next number and increases the equation
counter.
</warning>
<\warning>
We do not encourage the use of the AMS-<TeX> environments
<verbatim|align>, <verbatim|gather> and <verbatim|split>. Nevertheless,
they are available under the names <markup|align>, <markup|gather>,
<markup|eqsplit> together with their variants <markup|align*>,
<markup|gather*> and <markup|eqsplit*>. In the future, we plan to provide
more powerful environments.
