OMG! RPN logic was what distinguished the advanced from the amature when I was an undergraduate. This simulation is excellent. It's so realistic that I can't tell the difference, and it definitely helps at work. This is the calculator I now use exclusively, and I can't recommend it enough.
not bad initial display on 10" unreadably small. adjustable in the preferences. Stack doesn't roll on operator; this is abnormal for RPN, but may be correct for the 41cv. (I'm a 38g user...).
Truly amazing I can even put in the code I used to have in my defunct 41CV. Nice job. At the time, I bought a 2k memory pack to boost the calculator capacity. Now with my android platform I have 32Gb !!!
Nice idea, needs work The display might be alright for a phone but on a tablet, the keys scale but not the fonts on the keys on on the faceplate. In landscape mode, the unused portion is distracting. The emulation should include various module packs as who would use a HP41CV without the math pack and thermal pack. The faceplates on a 41C series were replaceable so the various optional faceplates as well as those with the module packs should also be emulated. As this is an open source product, there's a chance it may get better
This is the best calculator ever Thanks a million! I thought I would never see my old hp41CV ever again. And here it is right here on my favorite phone. Runs great on RAZR Maxx and droid Maxx
RPN is king As a student I programmed the teacher's brains out with HP calculators (once they allowed us touse them). Only time I was ever any good @ math.
Not much news in version 1.5.
Some bugs have been solved and the old layout removed as it was too dependent on screen size. This reduced the size of the app to a 1/4 of last version.
Problem with rounding in INT function solved
Problem with stack lost when the user switch to other apps solved
