![]() ![]() A peripheral / supplementary task where a calculation is needed in context in another app. I think the Calculator app is a good fit for the first and a somewhat poor (though capable) fit for the second. The second case is, perhaps, better handled by the on screen keyboard having a special calculation mode that can be automatically or easily invoked. ![]() This is work in progress and needs discussion with the Calculator maintainer.įor the service mode, this extension shows one way of integrating the service. See the Calculator extension (- BastienNocera 10:11:49) People have been known to type calculations into Google (and I know I regularly use Google to do currency conversions). One of the challenges of designing a modern calculator is to break out of the traditional "make a physical calculator on my screen" and make a tool that does useful calculations for the user. There's also a challenge to get the right balance between a tool that is good at mathematics (e.g. matlab) and a tool that is highly accessible to all users. GCalctool has been over time trying to push the envelope here (been stalled for some time though due to lack of developer effort). Being able to store results (using a history and variables, M+, MR are horrible hangovers from old physical calculators).the answer from meters to feet or UDS to EUR) Providing a method of converting units (e.g.999999999 type answers to some calculations which is confusing) Being correct in base 10 (some calculators use base 2 internally and show.Using correct notation where possible (e.g.Supporting equations up to the complexity of polynomials.Features that I think a design should aim for are: Note that GCalctool has an internal division between the GCalctool UI and the calculation engine so it would be suitable for embedding into other applications (was refactored for this purpose some time ago). (- RobertAncell)Īdvanced modes are often seen as "scary" due to the overwhelming number of buttons. A large portion of the visible space ends up being used by these buttons. Why do we even have them? I think they are just there because that's how physical calculators appear. Since we know the user has a keyboard (physical or on-screen) why not just get rid of the buttons? Then there is no need for multiple modes and we just need a few buttons for specific keys that can't be entered (e.g. pi), modes (superscript and subscript) and handy macros (exponential numbers).For students who need a calculator that offers memory, trigonometric, graphs or even factorial functions, this list of 15 free calculators for use on your laptop, desktop or mobile device will get you started with solving complex equations.Īll operating systems provide a calculator, but most offer only basic mathematical functions such as addition, subtraction, multiplication and division.
