 A Simple Complex Number Calculator for GTK+

 Author: SAITOH Akira

     This is a simple scientific calculator for complex numbers.
   The real part, imaginary part, absolute value, and argument of
   a complex number can be input.
     As this is a simple one, if matrix calculation is needed, a
   more scientific calculator is proper, such as Rascal or Octave.
   See the manual page for details.
