    DB50X is a new high-precision scientific calculator inspired by the legendary HP50G series from Hewlett-Packard.
    It is not an emulator, but a redesign from scratch, which is faster, and delivers never seen before capabilities like computations in arbitrary precision.

    Like the original HP50G, DB48X supports an unlimited stack, RPN and algebraic operations, complex numbers, based numbers, vectors, matrices, text, symbolic computations, numerical solving and integration, graphing and plotting, statistics, engineering units, and well over 1000 built-in functions. It integrates a library of equations and constants covering mathematics, physics or chemistry.

    Using modern technologies, DB50X goes well beyond the original HP50G in many ways:
    - It is significantly faster, uses less memory, and features a higher-resolution 240x400 pixels graphical color display.
    - Integer and decimal values can have an arbitrarily large number of digits, so you can compute log(pi) with 200 digits in a few keystrokes.
    - The six function keys feature up to three function per key, giving quick access to up to 18 related functions at a time.
    - Complex numbers can mix and match polar and rectangular form.
    - Symbolic operations extend to complex numbers, vectors and matrices.
    - Based numbers can be in any base from 2 to 36, and support any number of bits, making it easy to emulate a 23-bit or 512-bit processor.
    - Text is represented using Unicode instead of the proprietary HP encoding, facilitating data exchange with the rest of the world.
    - Multiple graphs can be distinguished using colour patterns
    - Engineering units include all the modern evolutions of the SI system, and can be configured by the user, e.g. to integrate currency units with the exchange rate du jour. Converting between USD/hour and EUR/day has never been so easy!
    - A built-in hyperlinked help system documents functions simply by holding the corresponding key, and combine a quick start guide, a user manual and a reference manual.
    - Over 700K of memory is available for RPL programs.
    - Access to iCloud to save your program and edit them from your Mac.

    DB508X will run many user RPL programs designed for the HP48, HP49 or HP50 directly as is.
    However, since it is not an emulator, it will not run any HP binary object, and notably will not run HP50G games or anything involving system RPL.

    Version 0.7.14 is an early-access release. Please consult https://github.com/c3d/db48x/blob/stable/doc/5-Unimplemented.md for a list of commands that are not yet implemented.
    DB50X is part of a family of related calculators that include the black-and-white DB48X and the entry-level DB40X.

    This release focuses on various user interface aspects. It introduces support for the User mode (key assignments) and a custom header (for example if you want to show the path or other information in the header). Also, the builtin help now automatically adds hyperlinks for all the commands referenced in the documentation.

    It also fixes a number of bugs, including a serious one that could cause memory corruption while editing.

    The primary focus of this release is to support the work on the equation library done by Jean Wilson, notably with the introduction of a multiple-equation solver, the possibility to load code examples from the built-in help (which was also accelerated), and support of copy-paste in the simulator. The solver work is not finished. The MSLV (multiple simultaneous equation) solver is not implemented, and I am unsatisfied with the current behaviour of the simple solver when there are no roots (it does not converge quickly enough towards an extremum).

    Additional improvements are suggestions by users, notably support for polar, spherical and cylindrical vectors, faster typing for Greek and Cyrillic, and quick edit commands using transient alpha with function keys. There is also a fix for the display bug causing 500.000 to display as 500000 and a fix for a precision problem for arctan for inputs between 0.5 and 1.0.

    Like for complex numbers, spherical and cylindrical vectors are not just a display artefact controlled by some flag, so that the stack can contain a mix of cylindrical, spherical and rectangular vectors.

    The Greek and Cyrillic entry improvements are a change in the default alpha keymap when the Greek or Cyrillic character menu is selected, where related letters are selected. Multiple presses on an alpha key will cycle through possible options. For example, in lowercase mode with the Greek character menu selected, typing E gives you ε, a second press gives you έ and a third press gives you e. Then it cycles. The mechanism is easy to configure and extensible, so that you can build your own character keymaps (math, French, etc)

    The quick edit commands using transient alpha mode also derive from discussions with Jean Wilson. It gives you the first two levels of menu commands in the EDIT menu by holding UP/DOWN (LEFT/RIGHT) and F1-F6. For example, ▶F3 is a quick way to get the "next word" command, ▶F1 gives you Select (start a text selection), ▶F5 gives you Cut, ▶F6 gives you Paste, and ▶F4 gives you Search.

    应用描述

    DB50X is a new high-precision scientific calculator inspired by the legendary HP50G series from Hewlett-Packard.
    It is not an emulator, but a redesign from scratch, which is faster, and delivers never seen before capabilities like computations in arbitrary precision.

    Like the original HP50G, DB48X supports an unlimited stack, RPN and algebraic operations, complex numbers, based numbers, vectors, matrices, text, symbolic computations, numerical solving and integration, graphing and plotting, statistics, engineering units, and well over 1000 built-in functions. It integrates a library of equations and constants covering mathematics, physics or chemistry.

    Using modern technologies, DB50X goes well beyond the original HP50G in many ways:
    - It is significantly faster, uses less memory, and features a higher-resolution 240x400 pixels graphical color display.
    - Integer and decimal values can have an arbitrarily large number of digits, so you can compute log(pi) with 200 digits in a few keystrokes.
    - The six function keys feature up to three function per key, giving quick access to up to 18 related functions at a time.
    - Complex numbers can mix and match polar and rectangular form.
    - Symbolic operations extend to complex numbers, vectors and matrices.
    - Based numbers can be in any base from 2 to 36, and support any number of bits, making it easy to emulate a 23-bit or 512-bit processor.
    - Text is represented using Unicode instead of the proprietary HP encoding, facilitating data exchange with the rest of the world.
    - Multiple graphs can be distinguished using colour patterns
    - Engineering units include all the modern evolutions of the SI system, and can be configured by the user, e.g. to integrate currency units with the exchange rate du jour. Converting between USD/hour and EUR/day has never been so easy!
    - A built-in hyperlinked help system documents functions simply by holding the corresponding key, and combine a quick start guide, a user manual and a reference manual.
    - Over 700K of memory is available for RPL programs.
    - Access to iCloud to save your program and edit them from your Mac.

    DB508X will run many user RPL programs designed for the HP48, HP49 or HP50 directly as is.
    However, since it is not an emulator, it will not run any HP binary object, and notably will not run HP50G games or anything involving system RPL.

    Version 0.7.14 is an early-access release. Please consult https://github.com/c3d/db48x/blob/stable/doc/5-Unimplemented.md for a list of commands that are not yet implemented.
    DB50X is part of a family of related calculators that include the black-and-white DB48X and the entry-level DB40X.
