CC

CC -- the class of all complex numbers.

The symbol ii represents the square root of -1.

     i1 = z = 3-4*ii
     
     o1 = 3 - 4 ii
     
     o1 : CC

     i2 = z^5
     
     o2 = - 237 + 3116 ii
     
     o2 : CC

     i3 = 1/z
     
           3    4
     o3 = -- + -- ii
          25   25
     
     o3 : CC

Here are some functions for use with complex numbers.
