- 4 Statistics Apps for descriptive and inferential statistics and data collection
- 4 graphing apps to explore graphs and tables of values
- 3 Explorer Apps for investigating the relationship between the parameters of a function and the shape of the function’s graph
In addition to these apps, there are four more apps of particular interest:
- The Advanced Graphing App allows you to plot and explore the graphs of functions and relations in x and y, including implicit relations, inequalities, and conic sections
- The Geometry App gives you the features of a dynamic geometry application, but with a Symbolic view for defining geometric objects exactly using the CAS
- The Spreadsheet App in which the CAS engine works.
- The Data Streamer app lets you collect data from sensors
The CAS is based on the open-source XCas engine, a powerful and advanced one, made to operate more like Maple, MATLAB, Mathematica, as opposed to something like the TI-Nspire's CAS, which is made to be "easy" and more direcly intuitive for students.
OS version history
- Pre-releases versions (from leak(s) and testers) : from revision 3xxx to 5106
These have been found on the DVT prototype models. Production models may have different components.
- Screen: Multi-Touch Color Display 3.5" diagonal with a resolution of 320x240px
- Processor (U101): Samsung S3C2416XH-40 - ARM9 (core: ARM926EJ-S) clocked at 400 MHz maximum.
- RAM Memory (U200): Hynix H5MS2562NFR - 32 MB
- Flash Memory (U201): Samsung K9F2G08U0C-SCB0 - 256 MB
- Battery: Li-Ion 3.7V, 1500 mAh (5.55Wh). A standard 2200 mAh Samsung Galaxy S3 battery can be used instead of the stock battery.
- Early / First (known) revisions (prototype):
- The calculator was named "HP Advanced Graphing Calculator"
- The back color is white
- The D-Pad was silver-colored
- DVT Prototypes:
- The calculator gets the name "HP Prime Graphing Calculator"
- The D-Pad gets black-colored
- Production models :
- The calculator gets its back color changed to black.
About half of the RAM (~ 16MB) is taken up by the OS, the other half is free.
- Very compatible with the HP 39Gii's BASIC. (mostly additions and fixes)
- Lists are array pointers.
- Objects work through reference counters. You can have a single object reference in many places - it could be hardcoded in the main memory, or a user object on the home screen, or a variable.
- All characters are UTF16.
- Once exported, functions act like they are built in.
- The advanced grapher uses interval based math, and cannot be mixed with user functions.
No native code (C/ASM...) programming capabilities are offered by default.
HP provides a free HP-Prime simulator for Windows.
No actual emulator (official or third-party) has yet been created.
