The '''HP Prime Graphing Calculator''' is a graphing calculator introduced by Hewlett-Packard in 2013 and manufactured by HP Inc. until the licensees Moravia Consulting spol. s r.o. and Royal Consumer Information Products, Inc. took over the continued development, manufacturing, distribution, marketing and support in 2022. It was designed with features resembling those of smartphones, such as a rechargeable lithium-ion battery, full-color touchscreen display, and a user interface centered around different applications.<ref>{{cite web |author-last=Seifert |author-first=Dan |title=HP's new Prime graphing calculator fights smartphone envy with a touchscreen and apps |url=https://www.theverge.com/2013/4/23/4256398/hp-prime-graphing-calculator-smartphone-envy-touchscreen-apps |publisher=The Verge |access-date=2013-11-06 |date=2013-04-23}}</ref> It claims to be the world's smallest and thinnest CAS-enabled calculator currently available.<ref name="DataSheet" />
The functionality of the HP Prime is also available as emulation software for PCs and Macs,<ref>{{Cite web|url=http://www.hp-prime.de/en/category/13-emulator|title=Emulator|website=HP Prime Calculator Portal}}</ref> as well as for various smartphones.
== Design and software == The HP Prime's graphical user interface features two separate home screens, one of which contains an integrated computer algebra system (CAS) based on the free and open-source Xcas/Giac 1.5.0 engine, which evolved from that of the HP 49G and its successors. Both the standard and CAS modes function independently of each other and the calculator can quickly switch between the two, unlike some of its competitors, such as the TI-Nspire series by Texas Instruments, which comes in either CAS-supported models or non-CAS models.
The G1 model calculator has a 1,500 mAh battery, which is expected to last up to 15 hours on a single charge. The G2 model comes with a battery with a capacity of 2,000 mAh.
Unlike the HP 50g and its predecessors, the HP Prime does not have an SD card slot and does not feature a beeper.
===Exam Mode=== The HP Prime has a feature called ''Exam Mode''.<!-- Other calculators incorporating an Exam Mode in 2015 were the TI-82 Advanced, TI-83 Premium CE, TI-84 Plus CE-T, TI-Nspire, TI-Nspire TouchPad, TI-Nspire CAS TouchPad, TI-Nspire CX, TI-Nspire CX CAS, Casio Graph 25+C, 35+E, 75+E. Who was the first to include this feature? --> This enables various features of the calculator (such as CAS functionality, user-created apps, notes, etc.) to be selectively disabled for a specific time, from 15 minutes to 8 hours. This can be done manually within the calculator's menus, or by using a computer with HP's connectivity software.<ref name="hpcc">{{cite web |title=HP Prime Graphing Calculator Exam Mode |url=http://www.hpcc.org/calculators/hpprime/WP_ExamMode.pdf |publisher=hpcc.org |access-date=2013-11-08}}</ref> LEDs on the top of the calculator blink to let the instructor see that the calculator is in this mode. Despite this feature, the Prime is still prohibited in many examinations, such as the US's ACT college-entry test.<ref name="tact">{{cite web |title=Can I use a calculator? |url=http://www.actstudent.org/faq/calculator.html |publisher=actstudent.org |access-date=2013-11-08}}</ref> It is however starting to be accepted in other examinations, like those run by the Dutch CvTE,<ref>{{cite web |url=http://www.examenblad.nl/nieuws/20150216/mededeling-vooruitblik/2017 |title=Mededeling vooruitblik hulpmiddelen CE 2017 en 2018 |publisher=Examenblad |date=2015-02-16 |access-date=2015-03-05 |archive-date=2015-04-02 |archive-url=https://web.archive.org/web/20150402170107/https://www.examenblad.nl/nieuws/20150216/mededeling-vooruitblik/2017 |url-status=dead }}</ref> the Swiss IB,<ref>{{cite web |url=http://forum.hp-prime.de/discussion/785/en-hp-prime-approved-for-international-baccalaureate-ib |title=HP Prime approved for International Baccalaureate (IB) |date=2015-02-17 |access-date=2015-03-08 |url-status=dead |archive-url=https://web.archive.org/web/20150402123836/http://forum.hp-prime.de/discussion/785/en-hp-prime-approved-for-international-baccalaureate-ib |archive-date=2015-04-02}}</ref> or Alberta (Canada)<ref>{{cite web |url=http://education.alberta.ca/media/6902701/06-dip-gib-2014-15_using-calculators-computers.pdf |title=Writing Diploma Examinations Using Calculators |publisher=Alberta Education |date=August 2014 |access-date=2015-03-05 |archive-date=2014-10-24 |archive-url=https://web.archive.org/web/20141024153416/http://education.alberta.ca/media/6902701/06-dip-gib-2014-15_using-calculators-computers.pdf |url-status=dead }}</ref> education authorities.
==={{anchor|PPL}}Programming=== The HP Prime's non-CAS home-screen supports textbook, algebraic and 128-level RPN (aka Advanced RPN) entry logic. Unlike RPL, which throws an error message when its dynamic stack is exhausted, the Prime's fixed-sized stack just drops values off the stack on overflow (like with four-level RPN).<ref name="Wessman_2016"/> The calculator uses a new operating system unrelated to HP's legacy Saturn and Saturn-emulated systems, which were used on HP's previous RPN/RPL graphing calculators; therefore, it is not compatible with any User RPL or System RPL, or with programming in Saturn or ARM assembler language.
The calculator supports programming in a new, Pascal-like programming language now named '''HP PPL''' (for '''Prime Programming Language''', but originally also referred to as HP Basic) that also supports creating apps. This is based on a language introduced on the HP 38G and built on in subsequent models.<ref name="introhp">{{cite web |title=Introducing HP Prime |url=http://www.hpcc.org/datafile/V32N2/IntroducingHPPrime.pdf |publisher=hpcc.org |access-date=2013-11-08}}</ref>

This model does not support wireless connectivity, unit-to-unit USB communication, or data streaming. The calculator is manufactured by Inventec Besta and utilizes a modified version of their Besta operating system.
The second production model (G8X92AA) reports its hardware revision as C. It was introduced in May 2014. This model supports features lacking in the first production model, namely wireless connectivity (using the ''HP Prime Wireless Kit'' (FOK65AA)), unit-to-unit USB communication (through USB OTG), and data streaming (using the ''HP StreamSmart 410'' (NW278AA) 4-port data streamer).<ref name="whichhw">{{cite web |title=Which hardware revision do you have? |url=http://www.hpmuseum.org/forum/thread-1457-page-2.html|website=Hpmuseum.org|access-date=2014-10-23}}</ref> The wireless kit includes a base station connected to a PC and wireless modules to connect to up to 30 HP Prime calculators for use in a classroom.

In July 2018, HP introduced a new hardware generation with model number 2AP18AA and hardware revision D. This version features an NXP i.MX 6ULL MCIMX6Y2 processor with ARM Cortex A7 core and is about three times faster. It provides more RAM (256 MiB instead of 32 MiB) and a bigger Flash module (512 MB instead of 256 MB)<ref>{{Cite web|url=https://fccid.io/R-REM-bta-HSTNJ-BC02|title = R-REM-bta-HSTNJ-BC02 HP Prime G2 Graphing Calculator}}</ref> and runs FreeRTOS.
