This command returns true if expr is of type algebraic (algebraic), and false otherwise.

An expression is of type algebraic if its top level type is one of the following:

$\mathrm{type}\left(2\,\mathrm{algebraic}\right)$

$\mathrm{true}$

$\mathrm{type}\left(\frac{1}{2}\sin \left(1\right)\,\mathrm{algebraic}\right)$

$\mathrm{true}$

$\mathrm{type}\left(a\left[0\right]+a\left[1\right]x\,\mathrm{algebraic}\right)$

$\mathrm{true}$

$\mathrm{type}\left(\left[1\,2\,3\right]\,\mathrm{algebraic}\right)$

$\mathrm{false}$

$\mathrm{type}\left(\left[1\,2\,3\right]\sin \left(x\right)\,\mathrm{algebraic}\right)$

$\mathrm{true}$

$\mathrm{type}\left(2<3\&comma;\mathrm{algebraic}\right)$

$\mathrm{false}$

$\mathrm{type}\left(\mathrm{series}\left(\sin \left(x\right)\&comma;x=\mathrm{\pi }\right)\&comma;\mathrm{algebraic}\right)$

$\mathrm{true}$
