說明
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.
