Assuming that you mean a decimal or rational expression, I think the answer is no.

#### Explanation:

$\arctan \left(0.5\right)$ is not a rational multiple of $\pi$. (See the discussion here: http://math.stackexchange.com/questions/79861/arctan2-a-rational-multiple-of-pi )

Furthermore, I do not believe that $\arctan \left(0.5\right)$ is rational in radians or degrees.
