Vicinno金融计算器

很漂亮，很好用的财务计算器。

有了它，我现在只有考试的时候用金融计算器了，太方便了！

提高运行速度呀

界面漂亮，RPN输入很神奇，但是软件有BUG，在竖屏模式下进入菜单后再返回屏幕是乱的。

很好

先学习，再使用。

有点深奥 用不好

Got my first HP in 1973, an HP35. Yhe Reverse Polish Notation makes everything SO much easier than direct algebraic entry. It is absolutely gabulous to have this app available.

I’ve been using this app for many years. It is one of my daily go to apps. No exaggeration. I use this every single day. If you’re familiar with the HP-12c, you’ll be completely familiar with this. I’ve never had a problem with it. It just works. A special shout out to the developer. Years ago, they gave the app a new, sleek, flattened look. I wrote to them about the fact that, due to my vision, I couldn’t see the demarcation of the buttons. The developer restored the original look as an option, which you can find under settings. Thank you for maintaining that. Some may be put off by the unfamiliar way of doing a simple calculation using what is called RPN notation. In school we learned PEMDAS-based arithmetic notation to enter numbers for calculations. Try spending a little time learning RPN. It helps get rid of parentheses and you control the order of arithmetic operations. It’s better for any multi-step problem other than adding a simple column of numbers.

Calculator opens at about twice the size of my iPad screen making half the buttons inaccessible. No resize of scroll function available. Worse, no way to get refund! Do not purchase for iPad!
