  • RPL implementation

    All basic features of RPL are implemented, including control structures, loops, conditionals, local variables, global variables, stack operations. This is a milestone where it's possible to transpose existing RPL programs from the HP48.

  • Numerical solver and integration

    Implementations of the solver and integration feature are complete enough. This milestone means that the calculator has the two signature features of high-end HP calculators.

  • Graphics

    Graphics operations make it possible to draw simple graphics, but also to plot functions. This milestone makes it possible to use the calculator as a graphing calculator.

  • Computer algebra

    The computer algebra system is functional and can be used to perform sophisticated symbolic manipulations. This is a key milestone because when it is reached, symbolic operations are essentially on a par with the HP-48.

  • Mathematics

    All mathematical objects are implemented and their behaviour on arithmetic and basic functions is sane. This means that you can perform operations on all major data types, including complex, vector or matrix objects. This is a big milestone because at this point, the calculator works as a calculator, even if it's missing graphics or if the computer algebra system is not complete.
