Introduction. +---------------- + +This is v5.32.0 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 MATE CVS repository, it was renamed to gcalctool. + +More recently, Sami Pietila provided arithmetic precedence support and +Robert Ancell converted the UI to use Glade. + + +4. Acknowledgements. +-------------------- + +See the AUTHORS file. + +---------------------------------------------------------------------------- + +Suggestions for further improvement would be most welcome, plus bug reports +and comments. + +The Gcalctool Team. |
