Is it true that it's impossible to put square roots in cogs?

That's true.

You could use the Heron method.

It's easy to program, but I dunno if its possible in cog, but I think it should.

here's the method programmed in pascal.. just translate and you're set


program heron;
uses crt;
var
zahl, wurzel,x,y,hilfe:extended;
begin
clrscr;
writeln("Number");readln(zahl);
y:=1;
wurzel:=zahl;
if zahl<1 then
begin
hilfe:=zahl;
zahl:=y;
y:=hilfe;
end;
while wurzel > <+0.0000000001 do
begin
wurzel:=(wurzel+y)/2;
y:=zahl/wurzel;
end;
writeln(wurzel);
end.

that one line should read
while wurzel > y+0.00000001 do

Sorry, I meant there is no specific verb for it.

Yes I have a cog that will do square roots ... I'll give it to you soon.

Well since I've learned about the existance of VectorLen(thing) I don't need the square root thing anymore (It was intended to find the speed of player moving)
