Ang: Yet another project idea

[Mats Lundälv]

Hi all,

 

Another try to post this to the whole group - the first mail was a bit too big to pass the 75K limit - this one should make it through - I hope ;-)

Thanks for your off-line reply John! /ML

A good free and accessible cross-platform calculator is a good idea indeed!

The on-line one you pointed to is nice, but with the disadvantage of being just on-line of course. There is also a need for a more basic version.

We have a rather nice one in Sweden called Calc On, which was developed in cooperation with with a developer called pmasoft (Slovakian if I remember right). You ca check out their freeware pmacalc at http://www.pmasoft.net/download.htm

The nice thing with the version they did for us in Sweden is that it calculates according to priority rules, is adjustable in size and display, and records and displays the history of what you do (in two alternative formats). Add some good speech support to that, and I think it would serve as a rather nice spec for a FOSS cross-platform basic calculator app, e.g. in Java. Scientific calculator features should of course ideally be added as options.
I include a couple of screendumps here as a hint of the settings options etc.

Cheers,

Mats


A medium size config without on-screen keyboard - std display of calculations history (both vertical and horizontal) - numbers can be edited in the history - calculations can be saved, or exported to an Excel spreadsheet.

The largest size - below full-screen - with so called "function" layout of history (just horizontal) - full support for parantheses in expressions.

Hi peeps,

 

On the vi-forum of which I am also a member, there has been concerns about Scientific Calculators not following the BODMAS (or BIDMAS rules if you prefer) in mathematical operation - as far as I know the only ones that do have too small a screen for a VI person to view (apart from an online calculator at: http://www.ilc.org/aat/calc.php

Sadly the Gnome Calculator doesn't follow BODMAS either (based on using the Gnome Calculator provided with Linpus Lite).

It would be good to develop some VI programs that are Open Source on a Memory Stick that are curriculum orientated that don't require GNU/Linux to run (even though it is much better than any other OS on the planet!).

 

Best regards,

John Blake (if only I could code!)
