Hello Curta fans,

I would like to know which approximation method you use to calculate square roots, or which one you know?

... To be honest - I have once according to this instruction (Quadratwurzel nach Toepler) the example recalculated. Also in the Curta Handbook by Bernard Stabile there is a solution for square roots... But would certainly not be able to calculate a square root without instructions!

Maybe I should practice a little Smile

Thanks murff.

Some time ago I discovered another (easier) way to calculate square roots - unfortunately I don't know where I found this approximation method.

https://docplayer.org/32458491-Zur-berechnung-von-quadratwurzeln-mittels-mechanischer-rechenmaschinen-detlef-kraus.html

Formula [5] on page 4 is the one I'm using - it's easy and you don't need any aproximat value or anything else.
