The
HP Prime is a
graphing calculator manufactured by
Hewlett-Packard (
HP). It contains features common in
smartphones, with a
touchscreen and
apps available to put onto it.
[5] There are two sides to the calculator, a numeric home screen and a
computer algebra system (CAS) homescreen. The calculator can quickly switch between the two, unlike its competitors, which either have a CAS model or a non-CAS model. The CAS is based on the free and open-source
Xcas/
Giac 1.1.2 engine by
Bernard Parisse, who was also the main developer of the CAS system integrated into the
HP 49G and successors. The calculator has a 1500 mAh battery, which is expected to last up to 15 hrs on a single charge. A
Prime emulator PC software is available as well.
It has also, for now (2014), taken the title for the world's smallest CAS calculator at 18,23 x 8,58 cm and is also the thinnest CAS calculator available currently, with a thickness of only 1.39 cm.
