  • 4 Solver Apps for solving specific types of problems (triangles, finance, linear systems) and a general solver for equations and non-linear systems
  • 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"[1] and more direcly intuitive for students.

Commands

The HP Prime has 3 classes of commands: HOME, CAS, and Spreadsheet.

Components

These have been found on the DVT prototype models[2]. 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)

Revisions

  1. Early / First (known) revisions (prototype):
    • The calculator was named "HP Advanced Graphing Calculator"
    • The back color is white
    • The D-Pad was silver-colored
  2. DVT Prototypes:
    • The calculator gets the name "HP Prime Graphing Calculator"
    • The D-Pad gets black-colored
  3. Production models, revision A :
    • The calculator gets its back color changed to black.
  4. Production models, revision C :
    • Unlike revision A calculators, this revision is supposed to be able to use the wireless adapters.

Modifications

  • Battery: The stock 1500 mAh battery can be replaced by a standard 2200 mAh Samsung Galaxy S3 one, providing a ~50% better capacity.

Programming

About half of the RAM (~ 16MB) is taken up by the OS, the other half is free.[1]

HP-Basic

  • Very compatible with the HP 39Gii's BASIC. (mostly additions and fixes)
  • Lists are array pointers.[1]
  • 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.[1]
  • All characters are UTF16.[1]
  • Once exported, functions act like they are built in.
  • The advanced grapher uses interval based math, and cannot be mixed with user functions.[1]

Native code

No native code (C/ASM...) programming capabilities are offered by default.

Emulation

HP provides a free Windows version of the HP-Prime software.
No actual emulator (official or third-party) has yet been created.

Reviews

On the market
