I am in need of a program that will allow a student to enter an equation in the form > b = 5 > s = 90 > w = 12 > x = b^2 + (s^3/w) The program needs to be able to do all basic math functions. * / - + sin() cos() tan() atan() acos() asin() log() sqrt() etc... I am about to write the program, but if there is one already floating around I will be grateful for a copy, or a pointer to it. The program is to be used as a teaching aid for one of our engineering courses. I will specialize it to fit the specifications of the course. Thanks in advance. -- Tony Galway Department of Enginneering Memorial University of Newfoundland tony4@stretch.cs.mun.ca||tony4@stretch.mun.edu||uunet!stretch.cs.mun.ca!tony4 Save the whales .............................. we'll need them for food later.

In Kernighan and Pike's book `The Unix Operating System', they develop a sophisticated calculator program called 'hoc4'. The back of the book has a full source code listing. I suspect many people have typed this code in by hand, so it may be available near you. If you can't find it locally, one of my colleagues here at Melbourne has typed it in, *and* fixed a few bugs in he code (sloppy mixing of pointer types, &c.), so i could post it if you like. -- Richard Brown | E-mail: pbrown@munda.ph.unimelb.EDU.AU School of Physics | Phone : +61 3 344 5081 University of Melbourne | Fax : +61 3 347 4783 Parkville Victoria AUSTRALIA 3052 | Telex : AA35185

If you have a Unix system, it's easy -- just use the "bc" calculator. If you feed it the above example and then say "w", it will say "60775".

Oops! You are absolutely correct. While I'm here, I should mention for the benefit of those who have written to me requesting the source code, that for various reasons it is not immediately available, but should be so in a week or thereabouts: be patient! Also, it seems that I have quite a few requests for this code, which makes me inclined to submit the source code to comp.sources.misc. However, since the code is published in the above-mentioned book, does that make the _source_code_ copyright? Can I post the source without infringing the copyright? rab --- Richard Brown | E-mail: rab@ariel.its.unimelb.EDU.AU School of Physics | Phone : +61 3 344 5081 University of Melbourne | Fax : +61 3 347 4783 Parkville Victoria AUSTRALIA 3052 | Telex : AA35185
