这是我在PALM pre上见过最好用科学计算计算器!功能强大!
4 U5 p; h7 \/ j# }1 i: N作者还公布源代码了.在APcatlog上卖9.9$,但是下载源代码后可以自己动手安装,也可以打包成ipk的安装包.2010.1.29 已更新至1.0.45版本，在1.3.5.1虚拟机上测试通过。新版本的说明和使用很齐全。建议更新。详见附件

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.4 l2 W6 j, _, p; v3 K
This 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.

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:

On a normal calculator you'd type '5 + 3 = '.

It's kind of like using paper to do calculations if you think of it.1 L; D8 b; I8 N
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'.* h9 G* S$ c1 c, {
Let's say you want to do the following:

On this calculator you simply type:$ z# }, g3 L4 ?& A$ D
'5 ENTER 3 *', then '2 /' and finally '7 +'. Pretty cool huh?
