The first one lets you turn K on or off
K.
From OKLAHOMA don’t have no clue, don’t why you think an Ok nerd would know over another state? /s

Damn, it worked.
Found some documentation listing the two middle switches as the rounding switch (up fraction down) and the decimal switch (auto? 0 to 6 then hex?). No idea on the other two.
http://www.calcuseum.com/SCRAPBOOK/BONUS/32853/1.htm
Decimal switch: [A-0-2-3-4-6-F], Round switch: [(ArrowUp)-5/4-(ArrowDown)], Miscellaneous switch: [(Blank)-K .-(Sigma)],
Nice!
Some guesses by ChatGPT:
Left Switch (“K” setting):
- 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).
This looks mostly right. The precision slider is definitely 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’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.
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
Can’t trust them to be correct,
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.
True.
Yeah, people are really bad at nuance and context. Even something that is normally a shitty tool can have uses.
At least it can give you more precise questions to google to verify its output
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.
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.
It kind of makes sense in that 15 is the last single digit in hex.
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.
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
Checks out, since floating point is “flyttal” in Swedish.
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?
No.
apology for poor english
when were you when svenska calculator post drop?
i was sat at home eating IKEA meatballs when notification ring
‘Calculator switch set to K’
‘no’
It’s an older copypasta sir, but it checks out.
Svenska Kalkylator.
Thanks, I already know no. means number
Nomber*
Wait, holy crap, why is No. short for number? Must have to do with another language?
Edited to add, of course the answer is Latin.
No.
Pretty sure its actually the calculator language

No means no, you misogynist pig!
No
Looks like Facit calculators were originally manufactured in Sweden and then later Japan. No mention of that particular model on this website, however
I know. I’m in Sweden. Facit was a big thing in its day. This one’s made by Sharp in Japan. It’s a 2102. Or maybe that’s when the manual will be released.
They seem to have some kind of function regarding how to perform or display calculations.
This app isn’t very intuitive
Well, I see a round up, didn’t round, or round down switch. The next one might be how many points if precision??. The last one has to do with sum vs series somehow.
That is interesting, though. Beyond me, that’s for sure
If I move the larger switch to A, everything is done in decimal. Maybe that’s a hint?
Trying to find the sum of my meme ransom please respond
On the top left you can change from none or K
Isn’t it decimal or K?
k
.
K
Switch seems to work at least
Now we’re getting somewhere

OK, SOME NERD PLEASE EXPLAIN THE SWITCHES ON THIS IRL CALCULATOR APP!
