Not worth of it
Don’t waste your money!

Plus42 is even better!

Perfection
Once you use an RPN calculator, you will never go back. The HP-42S beats the HP Prime in layout and ease of use for most task, and the enhancements in this implementation is great. I love having the (enhanced) HP-42S always with me on my iPhone whenever I need a calculator.
Can’t convert from DMS to decimal degrees!
WTF. It can easily convert decimal degrees to DMS, but not DMS to decimal degrees?!? What is the point of having one but not the other?!?
Response from developer
The function to convert degrees/hours, minutes, and seconds to decimal degrees/hours is called →HR. It's in the CONVERT menu, right next to →HMS. Note that I would have noticed your comment much more quickly if you had emailed me. This space is for app reviews, not for tech support.
Great calculator, however
I’ve really like this calculator however lately there seems to be an issue with programming. I had a program for the sulfur to convert Celsius to Fahrenheit and vice versa but for some reason it doesn’t work anymore so 212 Fahrenheit should be 100 Celsius. it comes up with something like minus one point something to the power of 6000 I wonder what the issue is?
