is a open-source calculator very fast and easy to use
, a useful additional tool to perform simple as well as trigonometric calculations.
Inspired from HP calculators,
QeasyCalc runs using the Reverse Polish Notation system (RPN), in which
the operators folllow the operands. For instance, to add the numbers
seven and eleven, one would write "7 11 +", rather than "7+11".
Intermediate results are stored into a stack, which make complex
calculations more efficient and the use of brackets unnecessary. Also,
the results of the calculations are easier to check.
With QEasyCalc, it is possible to perform a huge number of operations,
thanks to its almost infinite stack. For more information about the
Reverse Polish Notation, please refer to wikipedia.
has been designed and developed with Qt.4 and can run on Linux and Windows environments. The application can be downloaded for free on this webiste. Download
QEasyCalc is a user friendly and flexible tool. The
default settings can be easily changed and the user can customize the
calculator to his own preferences. The virtual keyboards can be moved
to any place of the screen, and even removed if the user perfers to
type in using the computer's keyboard. Depending of the number of
calculations to perform, the screen can be resized to adjust the size
of the stack of values to display. The page Documentation describes all
the functionnalities of the calculator.
