 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.

   * 21 Mar. 2017: An icon for the window title bar has been added for Unix-like environment. (2.2.4)
   * 15 Mar. 2017: Changes in the clipboard handling code for the MS Win 32 environment. (2.2.3)
   * 12 Mar. 2017: An icon file has been added for the use in the MS Win 32 environment. (2.2.2)
   * 18 Jul. 2016: Some configuration files have been updated for package building in the recent software environment. (2.2.1)
   * 2 Jan. 2016: Buttons "re z" and "im z" have been added and the layout has been slightly changed. (2.2.0)
   * 30 Dec. 2015: The latest development version has been put into the git repository.
   * 11 Aug. 2011: It has been confirmed that the present version 2.1.9, albeit a little old now, compiles fine in Fedora 15. In addition, the present binary RPM files work fine in Fedora 15 (both 32-bit and 64-bit). The binary setup file for MS Win 32 works fine in Windows 7 (both 32-bit and 64-bit). (just information)
   * Slight modifications have been made so that a package can be created using recent versions of GCC and RPM without warning or error. (2.1.9)
   * The text for Help and manuals have been updated. (2.1.8)
   * The inconsistency in the function Paste has been fixed: in this version, "a-ib" is regarded as "a-bi", is not regarded as "a". (2.1.7)
   * The accuracy of the calculation of the gamma function has been improved so that it returns a correct value for an input complex number with a negative real part and a very small imaginary part. (2.1.6)
   * A modification has been done so that it can be compiled with gcc-3.4.x without warning during compilation under 64-bit environments (with GTK+-2.x.x or with GTK+-1.2.x.) (2.1.4)
   * The "mod" function has been modified so that it works as an ordinary "mod" for real-number inputs, e.g., -3 mod 5 = 2. (2.1.3)
   * The accuracy of complex-number calculation in the zcomplex library has been improved, particularly in inverse hyperbolic functions and inverse trigonometric functions. (2.1.0)
   * The default font size is modified, conforming to recent Linux distributions. (2.0.10)

 - Requirements -
  1. GTK+-1.2.x or 2.x.x and some UNIX system are required to compile source codes.
  2. Binary files (x86_64 Linux and Win32 native) are also available.
   GTK+ is common in Linux distributions; the Win32 file contains the precompiled DLLs.
   Therefore, you probably need not to install the GTK+ libraries by yourself.
