user) Four AAA batteries, providing 50 hours of typical use, and one CR2032 battery Piezoelectric beeper Powered by battery or USB Over 800 built-in commands, performing thousands of functions HP part number F2229AA (Data Sheet) Calculating Environments RPL-style RPN (Reverse Polish Notation) EOS-style algebraic Equation Writer (textbook-style input) Stack display shows 7 lines by default, but it can be increased to 8 or 9 by shrinking or removing the header Header shows current directory path and important settings, and optionally can display a digital or analog clock Expandability SD card slot, with support for industry-standard cards up to 2 GB formatted as FAT16 (full support) or FAT32 (partial support) (Note: cards larger than 1 GB will have their free space misrepresented by Filer due to insufficient room for the number of digits, but will otherwise work fine) Communications Infrared (IrDA and HP 82240B thermal printer supported) USB (cable included) RS-232 serial (cable available separately) Programmability Five built-in programming languages: User RPL, HP Basic, System RPL, Saturn assembly, ARM assembly Compilation and decompilation of code built-in, along with limited debugging support Programmable in C using a PC and third-party software (HPGCC) Built-in tools for hacking the internal operating system and creating system libraries Full access to all built-in commands, including all stack operations, branching, testing, graphics, time, input and output Customizability Fully-redefinable keyboard Four different font sizes Font editing Three built-in languages for messages (English, French, Spanish) Applications Text editor with copy/cut/paste and find/replace functionality, plus multiple fonts and styles Matrix editor displaying seven rows and four columns by default Equation writer with easy-to-use interface for entering expressions as they would be written on paper (similar to MathCAD) Clock with alarms Finance (time value of money and amortization) Graphing 2-D Function, Polar, Parametric, Differential Equation, Conic, Truth, Histogram, Bar, Scatter, Slopefield, and multiple 3-D modes Determine roots, intersections, slope, area, extrema Zoom, trace, find coordinates, and shade plots Plot multiple equations simultaneously Table of values Probability and Statistics Σx, Σx2, Σy, Σy2, Σxy Sample standard deviation, population

conversions from decimals to fractions in terms of π and radicals, or between proper and improper fractions Decimal functions, finding the integer and fractional parts, the floor and ceiling, the mantissa and exponent, the sign, and rounding or truncating to a specified number of decimal places or significant figures List processing, performing operations on multiple numbers at once, as well as calculating the sum, product, and differences, and sorting Discrete Fourier transform and its inverse Complex numbers, both with decimals and infinite precision integers Summation Software Library
