Comment on Ok, some nerd please explain the switches on this IRL calculator app

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/Σ/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).
