Use complex numbers. They are part of python (no special modules needed). Just write your real number r, as r+0j e.g. square-root of -4 is 2j >>> (-4+0j)**(0.5) (1.2246063538223773e-16+2j) # real part is almost zero >>> >>> (-4.234324+0j)**(0.5) (1.2599652164116278e-16+2.0577473119894969j) >>> 2.0577473119894969j ** 2 (-4.234324+0j) >>> Karthik -- http://mail.python.org/mailman/listinfo/python-list
