      In this paper, we present a fast and fraction-free procedure for determining the zero-location of an algebraic equation with integer coefficients in any rectangle area in complex plane, where the polymomial is squarefree and monic, and the coordinates of the vertices of the rectangle are integers. In order to address the stability problems, we use exact arithmetic only.
