K: Likely for a “constant mode,” where the calculator uses one operand as a constant for repeated >calculations (e.g., multiplying several numbers by the same value).
The other position is likely “normal mode,” disabling this feature.
Middle Switch (“A/2/4/6” etc.):
This could control decimal rounding or precision:
“A” might stand for “automatic” mode.
“0, 2, 3, 4, 6” refers to the number of decimal places displayed or used in calculations.
“F” likely stands for “full precision,” using all available decimal places.
Right Switch (“Σ” setting):
Σ: Likely enables a “summation mode,” where the calculator automatically adds results to a running total (useful for bookkeeping or repetitive additions).
The other position disables this mode.
Being Swedish the “constant mode” seems likely as we often used k (for “konstant”) in school math to represent a constant (e.g. for the slope of a line).
Bold of you to mention chat gpt in a comment, I feel like any mention of it tends to get down voted to hell, even when it’s appropriately used as you did here
Those fucking things are great as tools to figure stuff out. Can’t trust them to be correct, but you can trust them to shoot the shit and dribble the ball to a destination which is unknowable to man
At some point people somehow got the idea that if you blindly trust something, bad things that come from that aren’t your fault. People definitely aren’t skeptical enough. That’s the problem.
Until I saw your post, I was going to guess the A,0,2,3,4,6,F switch would switch it into different numerical bases. Like, if you wanted to do math in binary, switch to the “2” position. “0” (or maybe “A”) would be base 10. “F” would be hexadecimal. But what you have definitely makes more sense.
This looks mostly right. The precision slider is definitelyprobably only for the output, not calculations. The (up | 5/4 | down) is (always round up | round 5+ up and 4- down | always round down)
What I’d like to know is how the A and F settings are different.
Auto to me (if A is Auto) sounds like it’d truncate unnecessary digits (4 or 4.0 instead of 4.0000) maybe? Whereas if F is Full then you’d get full precision?
Idk seems logical but not especially useful, probably not a great guess.
I can say that A seems to be Auto in the way you think but I haven’t figured out what criteria it has for this automation. Maybe there’s a way I could figure it out. I’m not a maths kind of guy (had pretty bad teachers in school) so it’s all honestly above my head. Shamefully enough.
I noticed that too, but they are coprime with one another and they aren’t divisible by or into 10, so they would definitely create repeating digits. Could’ve used 1/3 for the same effect though.
I just tried and it’s a pi approximation, which makes more sense.

True.
At least it can give you more precise questions to google to verify its output
Yeah, people are really bad at nuance and context. Even something that is normally a shitty tool can have uses.

F is 15, so that’d be weird for hex, and I’ve never seen base 4 or 6 used for anything, base 8 is common for some things but missing here.
I think some computers have been known to work in base 6. Or maybe I’m just confusing it with them using 6 bits. Probably the latter.
6 bits per digit, 12 bit words. Octal (8) number system.

i’ve never seen one of these display decimals like that, it doesn’t seem like something that would need a setting.
Yeah I don’t think my comment is right lol.

Nothing to be ashamed of my friend, cool little device you’ve got here!
Did you just plug the picture into chatgpt? It’s awesome if something like that works :o
Yes I uploaded the image and asked it the same question as OP
Yeah, I use that feature all the time. It’s really great. I can upload an image of text data and get an output in table or summary format.
Did you literally ask some nerd to explain this app? Thank
It seems to be right on the K switch. And yeah. Konstant makes sense.
The numbered switch seems to check out at least. Other than the F. F just gives me a single decimal. edit: no… Three…?
Not sure about the right switch. It adds an I in the upper right corner and it seems possible to flip between different calculation results. Maybe?
F is likely Floating point - so, just regular precision. Not sure what A would be, then
For checking F try typing in an irrational number. Like 22/7
Yeah that certainly worked
Photo for the nerds who like screens
Note: the display is actually a deep green to the eyes.
What does 22/7 get you under “A?”
Setting it to A and only punching the numbers divides 0.22/7 and results in 0.03.
Actually dividing 22/7 gives us some tasty π. 3.14.
did you just suggest a ratio as an irrational number?
Well he doesn’t have a pi button.
I wish I did but I ate a slice

Given the available context, I’m inclined to agree with ChatGPT. I can’t see those listed being anything else
