This map is a special case of the complex [[quadratic map]], which has exact solutions for many special cases.<ref>M. Little, D. Heesch (2004), [http://www.eng.ox.ac.uk/samp/members/publications/GDEA41040.pdf Chaotic root-finding for a small class of polynomials], ''Journal of Difference Equations and Applications'', '''10'''(11):949-&ndash;953.</ref> The complex map obtained by raising the previous number to any natural number power <math>z_{n+1} = z_n^p </math> is also exactly solvable as <math>z_n = z_0^{p^n}</math>. In the case <math>''p''&nbsp;=&nbsp;2</math>, the dynamics can be mapped to the binary [[2x_mod_1_map2x mod 1 map|shift map]], as described above, but for <math>''p''&nbsp;>&nbsp;2</math>, we obtain a shift map in the [[number base]] <math>&nbsp;''p</math>''. For example, <math>''p''&nbsp;=&nbsp;10</math> is a decimal shift map.
