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 _________________:: m u r f f :: curta.li

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._________________Type I 5023 8121 11140 22146 22961 22983 26713 66561 80151 Type II 500438 502852 507157 509135 555001 555476
