Questions about HP Prime G2

The HP Prime G2 is recommended for solving equation systems in statics. It offers fast computing power, a high-resolution touch display and efficient buffering, saving you time. The HP Prime G2 is particularly suitable for complex calculations and offers good value for money.

What do you mean? To calculate percentages you only need * and /. Basic value G Percentage p Percentage W p=W/G*100 W=p*G/100 G=W*100/p I leave out the factor 100 because you can simply take the number 0 for 0%, 0.5 for 50% and 1 for 100%. Then there is not much more to enter. Another possibility is to programme the formula yourself, but it is not really worth it given the simplicity of the percentage calculation.

Python and Pascal are supported.

I bought the HP Prime for my electronics apprenticeship on the recommendation of my physics teacher. Yes to all questions: Elementary charge: Shift>Units>Const>Quantum> q Field constant: Shift>Units>Const>Physics> ε0 Units: Yep. Electrotechnical programmes for e.g. Ohmic law are not built in. However, such programmes are available for download. (See https://www.hpcalc.org/prime/science/ ) If you want, you can add units to your own formulae by appending the unit to the number/variable, e.g. "100_(Ohm)". The units are correctly looped through, but the correlations are not calculated: "10_(V)/100_(Ohm)" results in "0.1_V/Ohm" (at least correctly represented as a fraction) and not 0.1A. You can also save any formula as a user formula. For example, I have stored a user function called "PAR2" for 2 parallel resistors with the function "1/((1/A)+(1/B))", which is then entered like this: "PAR2(100,330)" for 100 and 330 ohms, and internally "1/(1/100+1/330)" is executed and output correctly 75. Binary: yes, in different ways. There is also a screen that gives you a 64-bit bitmask where you can edit the binary field (change bits, shift, invert, etc) and input and output the binary, hex, decimal, and octal values: First save the input number, e.g. here decimal 12: Type #12d [Enter] Shift>Base Tap Edit on the display There are also other ways that I haven't really used yet. At ftp://ftp.hp.com/pub/calculators/Prime/ you'll find all the software and documentation from HP itself, including the "Virtual Calculator" simulator for Windows/Mac that albinmächl mentioned, as well as the connectivity software that lets you upload programs to the real or virtual machine. (The "HP Prime Pro" app for iOS is still available, but not free).

Yes

I don't know anything about a standby. After a while, it dims the display and then switches off after 5 minutes. However, the timer can be moved with a small programme, e.g. http://www.hpcalc.org/details/7636.

Yes, that is possible, you can see that in the following video after the last picture: https://www.youtube.com/watch?v=WF8tZP0uKu0
