| 17 | 1. Introduction. |

|---|
| 20 | This is v4.2.0 of gcalctool, the calculator application that was previously |
|---|
| 21 | in the OpenWindows Deskset of the Solaris 8 operating system. Sun Microsystems |
|---|
| 22 | Inc. have kindly given me permission to release it. |
|---|
| 23 | |
|---|
| 24 | It incorporates a multiple precision arithmetic packages based on the work |
|---|
| 25 | of Professor Richard Brent, who has also kindly given me permission to make |
|---|
| 26 | it available. |
|---|
| 27 | |
|---|
| 28 | There is a single graphics driver for Gtk2 included with this release. |

| 31 | 2. Getting started. |
|---|
| 32 | ------------------- |
|---|
| 33 | |
|---|
| 34 | See the file 'INSTALL' |
|---|
| 35 | |
|---|
| 36 | The manual pages also describe how to use gcalctool in detail. |
|---|
| 37 | |
|---|
| 38 | There is a TODO file included which lists current bugs, and the |
|---|
| 39 | enhancements that will hopefully be added in the future. |

|---|
| 42 | 3. Calctool history. |
|---|
| 43 | -------------------- |
|---|
| 44 | |
|---|
| 45 | Calctool was a project I worked on before I joined the OpenWindows DeskSet |
|---|
| 46 | engineering group at Sun. It was originally released to comp.sources.unix |
|---|
| 47 | in the late 1980's, and worked with many different graphics packages |
|---|
| 48 | including SunView, X11, Xview, NeWS and MGR. There was also a version |
|---|
| 49 | that worked on dumb tty terminals. |
|---|
| 50 | |
|---|
| 51 | It used a double-precision maths library that was a combination of the work |
|---|
| 52 | of Fred Fish and various routines that were in the BSD 4.3 maths library. |
|---|
| 53 | |
|---|
| 54 | A lot of people in the community provided feedback in the form of comments, |
|---|
| 55 | bug reports and fixes. In 1990, I started working in the DeskSet engineering |
|---|
| 56 | group. I was working for Sun Microsystems in Australia at the time, (having |
|---|
| 57 | moved there from England in 1983). |
|---|
| 58 | |
|---|
| 59 | I searched around looking for multiple precision maths libraries and found |
|---|
| 60 | a package called MP written in FORTRAN by Richard Brent. I converted it to C, |
|---|
| 61 | adjusted the glue between the resultant code and the calctool code, and this |
|---|
| 62 | went on to be the basis of the calculator that was in the OpenWindows DeskSet. |
|---|
| 63 | I also added scientific, financial and logical modes. This calctool was also |
|---|
| 64 | the basis of the dtcalc application that is a part of CDE (albeit I had |
|---|
| 65 | nothing to do with that). |
|---|
| 66 | |
|---|
| 67 | With its inclusion in the GNOME CVS repository, it was renamed to gcalctool. |
