HP HP48GX RPN Expandable Graphic Calculator Specifications

Hewlett-Packard's HP 48GX is the most powerful calculator in the 48 series, offering the same advanced calculation and programmability features as its siblings, along with expansion options that should appeal to power users and programmers. All this is made possible by the expansion card slot, which lets users expand the built-in memory from 128 KB to a maximum of 1.256 MB or install application software that adds more advanced features to the calculator.

The 48GX is no slouch. Its colorful array of buttons lets users tap into 2,300 built-in functions, 300 of which are built-in formulas and scientific constants that encompass the spectrum of the mathematical and scientific fields. It handles everything from basic algebra equations to advanced trigonometric and statistical calculations. Best of all, if the 48GX doesn't have a feature you desperately need, you can use the built-in object-oriented programming language to create functions from scratch. You can then label your creations and access them as you would any other feature that is integrated with the calculator.

The 48GX uses reverse polish notation (RPN, also called postfix notation), which can be difficult for beginners to grasp, but advanced students and professionals will appreciate RPN's elegance and relative simplicity. An optional connectivity kit lets users connect the device to a PC to download new equations and software, and the integrated infrared port lets you share data with other calculators or output your graphs, plots, or other results to a separately available infrared printer. Typical students may want to opt for a less expensive (and less expandable) calculator in the 48 series, like the 48G+, but for those who demand the best and may need more than 128 KB of memory, the 48GX is the clear choice. --T.
