- 1. Introduction.
- ----------------
-
- This is v5.28.1 of gcalctool, the calculator application that was previously
- in the OpenWindows Deskset of the Solaris 8 operating system.
- Sun Microsystems Inc. have kindly given me permission to release it.
-
- It incorporates a multiple precision arithmetic packages based on the work
- of Professor Richard Brent, who has also kindly given me permission to make
- it available.
-
- There is a single graphics driver for Gtk2 included with this release.
-
-
- 2. Getting started.
- -------------------
-
- See the file 'INSTALL'
-
- The manual pages also describe how to use gcalctool in detail.
-
- There is a TODO file included which lists current bugs, and the
- enhancements that will hopefully be added in the future.
-
-
- 3. Calctool history.
- --------------------
-
- Calctool was a project I worked on before I joined the OpenWindows DeskSet
- engineering group at Sun. It was originally released to comp.sources.unix
- in the late 1980's, and worked with many different graphics packages
- including SunView, X11, Xview, NeWS and MGR. There was also a version
- that worked on dumb tty terminals.
-
- It used a double-precision maths library that was a combination of the work
- of Fred Fish and various routines that were in the BSD 4.3 maths library.
-
- A lot of people in the community provided feedback in the form of comments,
- bug reports and fixes. In 1990, I started working in the DeskSet engineering
- group. I was working for Sun Microsystems in Australia at the time, (having
- moved there from England in 1983).
-
- I searched around looking for multiple precision maths libraries and found
- a package called MP written in FORTRAN by Richard Brent. I converted it to C,
- adjusted the glue between the resultant code and the calctool code, and this
- went on to be the basis of the calculator that was in the OpenWindows DeskSet.
- I also added scientific, financial and logical modes. This calctool was also
- the basis of the dtcalc application that is a part of CDE (albeit I had
- nothing to do with that).
-
- With its inclusion in the GNOME CVS repository, it was renamed to gcalctool.
-
- More recently, Sami Pietila provided arithmetic precedence support and
- Robert Ancell converted the UI to use Glade.
