HP35s Features, or not



#6

Hi all

I just got my hp35s the other day to replace the hp32sii I seem to have lost and while I really like it, I'm surprised that square roots and logs of negative numbers produce an error when the calculator is designed to handle complex numbers (my hp28s handles these conditions). Anyone else surprised/annoyed by this?

I'm also a little disappointed that there is no vector cross product function.

Oh well, it's still a good calculator with a great feel.

There has been some discussion about this, but after all it's an evolution of the 32S platform, not the 42 or 28/48 platforms. On my 32SII, square roots and logs of negative numbers also produce errors, even though the 32SII has complex support. The only difference between the 32SII and the 35s in that regards is that complex numbers take up two stack registers on the former, and only one on the latter.

I do wish the complex support were more like the 42S, but I'm still very pleased with the 35s overall!

There is a post about this but I could not find it. At least, you can get the square root of a negative number this way:

1. enter the number as a complex, example: -5i0
2. enter 0,5 and do x^y, complete exemple:

5 +/- i 0 enter
0.5 x^y
0.0000i2.2361

regards,

Miguel

Excellent suggestion, Miguel. Thanks.

Yes, very good. These should be things, like figuring out how to go from P->R and back that we should archive and add to list of things to include in "cheat sheet" to keep with 35s.
