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.
$ H3 W1 C) F$ t, [0 ~3 wThis 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.6 i' {3 y* i, q) q) y
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.6 ?7 ^+ N6 ^4 S- Q! H5 T& A! T
There is keyboard support for number entry and basic operations.5 ^; i9 x1 N( u! L* N
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:

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'." D# C) w3 F; |. R' [' c
