UPDATE v1.1.4: Upgraded the calculator to reduce the laggy UI of the calculator, as well as repaired the longclick and dragging features of calculator body. These features should now be considered fully operational.
An advanced RPN Scientific calculator for the BlackBerry PlayBook, modeled after the HP line of calculators, such as the venerable HP15C.

If this method is unfamiliar to you, please refer to this apps support website for a brief explanation on RPN calculators, as well as links to couple of other RPN tutorials on the internet.
Features of this calculator include: complete suite of numeric, trigonometric and hyperbolic functions, basic statistical functions, persistent memory, longclick supportto directly activate any buttons ffunction, floating point computation error handling, scalable constants, and complex number computation. This calculator has two layout modes, fullscreen and normal. In the normal layout, the calculator can be moved the any location on the screen by touching the topbar and dragging. Additional feature to be included in the future: onscreen help, drag and drop stack, multivariate statistics, physics constants database, unit conversion, user definable programs, financial and digital logic computational functions, user definable behaviore.g. haptic feedback, visual feedback, etc..
