DescriptionAs per B36: please UNINSTALL the existing app before installing B36 or higher. I had to change the app ID which means if you upgrade it won't overwrite but you'll end up with TWO calculators.
H$ @$ `" o5 H: O- xThis is a scientific RPN calculator, inspired by (but not exactly emulating) the famous HP 1xC range of calculators. It features a 4-level stack and tons of calculator features.% a9 ]5 D! E; z& y: q4 _* s
This application INCLUDES a full blown unit converter supporting 20 different properties and an enormous amount of different units to convert from and to within these properties.+ n0 @! F! ]; w8 e* o
There is keyboard support for number entry and basic operations.6 e) r7 u# M1 V
This application has a fully customized GUI and a lot of work has been put into making it look as pretty as possible. If you're not familiar with RPN calculators, here's some simple examples:

It's kind of like using paper to do calculations if you think of it., z! R' a5 W8 n0 Z
RPN really shines when it comes to more complex calculations where operator precedence comes into play and brackets would need to be used. This is because an RPN calculator has a 4 level 'stack'.

On this calculator you simply type:8 i: Q5 I9 s5 V1 K
'5 ENTER 3 *', then '2 /' and finally '7 +'. Pretty cool huh?$ o, ^! l8 |+ J! s( y/ `- d
This application is still under development which means there will be bugs. Feedback is more than welcome!
