It's main features are:

  • Simple use
  • Menu access to all functions defined in Wcalc
  • Menu access to a huge number of constants defined in Wcalc.
  • Intuitive entry of formulas.
  • Easy editing and 're-evaluation'.
  • Easy conversion between decimal, hex, octal and binary, both in input and output.
  • Works with fractional numbers in all bases.
  • Very configurable.


This program was written with the help of the GIMP toolkit (GTK+), a marvelous piece of work, and uses the gnome-print library to generate Postscript output. Of course, it was developed on Linux, using the gcc compiler suite and the Glade GUI development system. Graphics items were designed using the GIMP itself.
