The precision tag
Intro
An equation
[math]\displaystyle{ \frac{e}{\pi}=2y }[/math]
or an equation array or another example in another section
and set some tags into your INCAR file
PREC = A GGA = PE
And another section
and an array of equations
An eqnarray
[math]\displaystyle{ \begin{align} \frac{e}{\pi} & =\int_\Omega \psi (\mathbf{r}) d\mathbf{r} \\ a & = b \\ \end{align} }[/math]
