Description

A simple RPN calculator!

A simple reverse polish notation calculator loosely based on my trusty HP-32SII that runs on iPhone, iPad, and Apple Watch!

If you are familiar with HP RPN calculators, the operation of this calculator should seem very straightforward - albeit simplified. It can't be programmed, and it doesn't handle binary, or hexadecimal numbers.

But, it has a clean, simple interface with large, easy to press buttons. It has all of the functions required for quick calculations when your iPhone is handier than your computer or calculator.

And, remember those cool calculator watches from the 1980s? Unfortunately, none of them were RPN. RPN Calc brings a reverse polish notation watch calculator to the Apple Watch!

In addition to the standard RPN Calculator app that runs on iPhone, iPad, and Apple Watch, RPN Calc includes a handy micro RPN Calc Today Extension available for convenient access to quick calculations from the pull down Today screen.

Ideal for anyone used to RPN

This software works fine, and ideal for anyone well used to RPN, and who like me has trouble using ordinary calculators. Be careful with the FIX and SCI notation buttons otherwise you will be rounding too much and get silly results.

Beware of reviewers who don't understand what RPN is ! And by the way if you take the trouble to learn RPN it is much quicker and less accident prone than 'ordinary' systems; also no one will nick your calculator.
