Misses keystrokes, tan gives bad results
on March 17, 2010
Posted by: TVSadako
I got this calculator because of its large number of features and RPN mode, which I use exclusively. On initial inspection it appears to be great; it's visually attractive, easy to read, and the keys feel good. Unfortunately, it didn't take too long for me to realize that, at least in RPN mode, the calculator consistently misses keystrokes. Keying in 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 rarely gives the correct answer (45). Additionally, I found that the tan function gives slightly incorrect answers at values very close to 90 degrees. Try taking the tan of 90.0000001 and comparing the result you get to what your computer tells you. The tan error is a minor issue for me, but the missed keystrokes makes this calculator unusable.
No, I would not recommend this to a friend.

The only calculator in 20 years that matches the style and ease of use of the HP 32sII.

Love RPN, Hex mode could be better

It's rather annoying that when in Hex mode, entered numbers still default to decimal. Entered numbers should default to the current radix mode.
I would recommend this to a friend!

The HP35s is the best scientific calculator I have ever owned. I have purchased three (3) since my first one back in 1984. The only improvement I would like to see is the function keys layout. The function keys layout is presently vertical, but was horizontal on the old models. I would like the function keys layout to go back to horizontal (like the financial calculators function keys layout is now)
I would recommend this to a friend!

Works very good. Takes some time to get use to moving from rpn. Challenge is that calculator is not available in any stores in the community that I live. HP should consider bringing back older versions like HP25 and HP41. These are very good products for scientific community
I would recommend this to a friend!

The product seem nicer and better look compared to 33S. I have my old 33S and need new one for the NCEES exam. The operational functions are reverse to 33S, e.g. 1/x function need to be pressed 1st and then you need to press digit. Especially if you are taking exam w/ time management, you cannot perform functions continuously. You have to memorize your digits and then another operation. I like 33S as it was convenient. If HP use 33S operational way, I mean digits first and then operation, and other features from 35S, that will be so great.

I have owned over a dozen HP calculators starting with the HP-35. The 35s and the 45 were/are the best of the lot.
