I would love to find a scientific calculator application for my BB8700, especially one that allows reverse-polish-notation (RPN) entry, something like an HP 32S / 42S etc... is there something available?
The calculator app that comes with the 8700 is okay for basic stuff, but there are no trigonometric, exponential, or other useful functions... and its precision is very limited... try entering anything beyond 99 million... to enter 128 million, you need to enter 12.8 million, then multiply by 10.
I was looking for exactly the same thing and one of the users in this forum, patrickh, sent me an app he was working on about 7 months ago. It works well, some minor display inconsistecies, but I never heard from him again. Anyway, I have it on my BB and it is the only caculator I use due to the RPN. Patrickh, if you're out there, any update for us?
There are some free tools out there, guys! Check out this one http://www.bradgoodman.com/blackberry/ -- scientific calculator, engineering calcuator, triginometric calculator - and more! so far the best though not 100% user-friendly.
