What calculator do you use ?
Architect_1077:
TI-92, vintage. This thing still works! ;D
Tepe:
I use the HP-15C I got a tad over 28 years ago :P
Randall W. Lott:
I use a TI-89 Titanium and a HP 50g.

I use a Casio FX115MS, because it's one of the very few models that understands and supports engineering suffixes for powers of 10. So, for example, I can directly multiply 47n by 33.1k and get an answer of 1.5557m, without having to first think about converting the natural way I write and specify components into E-9 or E+3 or whatever. Stick the calculator in Eng mode and it gives results directly in picofarads, megahertz or whatever other unit is appropriate, not just x.yyyE13 which requires thinking.

After the hint from juiceking about calcultor apps I found a very nice app from a HP45s for my lumia 900
I allready used it a lot. It looks so rela, and because the 900 is a big phone it works great too. I was using it on my desk and one of the guys asked, " got a new calculator ? , nice, looks expensive" he did not noticed it was my phone.
Also found one for the ipad, from a HP42. This is a real woking picture of a 42 (but with added functions) as an extra it gives the stack and registers seperate in a box. It works well but i think the modern two line display showing X an Y stack at the same time is more usable, aso the fact it uses rectangulair and polar notation on one line instead of R in Y and jX in X ( or I do domething wrong) . ( but not as good looking as the leds)
I would love to have on old HP with the point-led display. But i think they are rare collectors items by now (and need a lot of batteries)
