Great app!

I dont rate 5-stars often. This app just works, and is exactly what I need for my work. It has become my go-to mobile calculator, and Ive tried out many. I use the finance calculations, especial cost/price/margin, everyday in my work. I checked the functionality of the RND button that another reviewer dinged the app for, and it works. Some of the functionality of the app is a little odd, an HP thing. I had trouble figuring out some other functions, and actually found a sequence of button presses that would crash the app. I emailed the developer, and within an hour had a link to the full HP manual for the calculator that I downloaded, and a request from them on how to replicate the crash so they could fix the bug. Great app, Excellent support!!
