Thread: MACalc calculator new version - RPN and Algebraic

  1. #1
    Default MACalc calculator new version - RPN and Algebraic
    A new MACalc version has been released.



    New functions have been added and I've included algebraic input mode support.

    For more info see http://web.newsguy.com/marcio/iphone/macalc

    Conversions is included with the calculator.
    Just press "Mode" -> "Conversions"

    Pretty cool, thanks for the new alg mode! And I see it kind of slides side to side for different views, although that seems a little inconsistent.

    This is very good!

    Why does this man not have a DONATE button??

    Suggestion:
    For switching screens, only use the top calculator screen part, and not just anywhere on screen.
    At the moment, if there is an inactive button, and I press it by mistake, the screen switches. That becomes annoying very quickly.

    Well done on this excellent app!

    MACalc was written as 2 separate calculators.
    A real number calculator (floating point calc) and an integer calculator.
    Each with its own set of registers, stack .....
    When you "tap" the display area you switch from one to the other.

    Yes, that works well.

    You know that swiping is also enabled and transitions side to side between views? (But not real reliably)

    It's a great app.

    Thanks, this is a nice improvement and things mostly work quite well.

    Two suggestions/requests:

    1) Switching between calcs is too awkward and touchy. It switches accidentally, yet doing it intentionally is not easy enough. Since this is rarely something you'd want to do mid-session, maybe it would be better to simply make it a choice in the preference screen.

    2) Any chance you could move conversions into a plist so it would be possible for the choices to be user modifiable?

    Thanks again!

    I can add an option to disable "tapping" in preferences. In that case a button would be added either when you press "menu" or "mode" to move from integer to float and back.

    As for conversions, I might support user defined conversions in the future.

    Just make the tap area the top calculator screen, and not the whole iphone screen. That way, when you press on an inactive button, it doesn't switch the screen.

    It doesn't work. I've installed by ssh.

    Bug: On my 1.1.1 decimals change doesn't work very well.

    I'm a little disappointed in algebraic mode - it isn't really algebraic, more adding machine.

    Try 3-6*9 = should be -51, comes out -27.

    I really appreciate the addition of algebraic entry, but the current method does not support order-of-operations. For example if you type 9+6*3 you get 45 where you should actually get 27. Is there any way to add full formula support so that you can type on a single line "9+6*3" and then you could do parsing on it to keep OOO intact.

  22. #20
    I think that it's normal because you don't respect calculus alg order, you must put "(" and ")": 3-(6*9)=-51 or 9+(6*3)=27.
