Subject: Re: square root question



You might try this web site which I found by going to www.google.com
and searching for square root algorithm.

Hope this helps you.  Note that this algorithm just keeps getting a
bigger square out of the rectangle represented by (x+y)(x+y)=x^2 +
2*x*y + y^2.

I have a book by J.E.  Thompson, "Mathematics for Self Study,
Arithmetic" written 1931 and re-issued in the 40's that explains the
square root and cube root algorithm.
