The newest calculator in the HP graphical stable. Programmed from scratch in native ARM code, and with a 127 x 256 pixels screen with gray levels, it is much faster than previous HP calculators and also than the competition. The solid feel makes it an ideal calculator for school, in particular for those countries that do not allow CAS devices in class. Here are some of the improvements over the previous HP39gs: Multi language support: from over 23.000 different characters, to help in many languages in contextual setting; A very powerful graphical engine - actually much faster than the competition; text formatting facilities in two different font sizes, with the capability of adding notes and images within them; USB connectivity And a high level programming language, that allows, among many other things, to define functions that behave as built in. The responsable of the development team likes to compare it as much closer to the 50g in capability than to the previous 39gs. You can feel what the calculator is about by downloading the free emulator software - included in the package and with powerful communication capabilities, so that you can write your own programs in a comfortable development environment and then transfer to your calculator: Condition: Brand New Package Includes: 1X calculator
