Calculator12 puts a rock solid HP-12C emulator on your iPhone, iPod touch and iPad, whether you need it for school or are looking to retire old faithful. What you get is true (albeit non-programmable) HP-12C emulation with 100% compatible operation keystroke for screentap and computational and operational reliability every bit as good as the original.But wait, there more! (sorry about that). Calculator12 is much more than just another simple copy. You have the option to work with cash flows in the cash flow diagram format, changing values or inserting/deleting cash flows with just a tap. Three independent cash flow scenarios can be evaluated side-by-side, and with capital multiplication you can evaluate an exit strategy for outside investors. Results can be emailed from Calculator12 so you don't have to redo things like an amortization schedule or comparative investment report at your lap or desktop. And you can see what was once hidden... the contents of the financial registers or optionally the stack are always displayed. For me at least confirming the accuracy of my entries relieves a lot of anxiety and prevents confusion when the results don't stack up. It's not programmable, but advance payment leasing functions have been pre-programmed in as well as conversions to APR and Effective Rate to fill some of the gaps. And it is blisteringly fast--what used to take 30 seconds now is done almost before your finger leaves the touchscreen. Calculator12 was the very first HP-12C emulator on the App Store, v1.0 released August 8, 2008, introducing features (now almost universally copied) that take advantage of the unique features of iOS to improve your ability to deal with financial problem solving. There are lots of emulators now, but only one that has moved out of the 80s. (this one!)*** This application listing provides an upgrade path for early adopters to the redesigned and renamed Calc-12E. It is identical to Calc-12E and is maintained on the App Store to provide a way for existing customers to upgrade their original purchase to Calc-12E free-of-charge... It will appear on your home screen as Calc12E***

Now with copy and paste! Double or long tap on the display and copy/paste between apps. When a new number is pasted, we do not automatically press the ENTER button so that you can change it after pasting. CAUTION: when pasting, the calculator respects the region format in "Settings, General, International, Region Format" so if you are pasting a number that was formatted in a different region the results may be unpredictable!Fixed a problem with the display when entering numbers at a fixed 2 deci...
