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. http://www.geocities.com/cnowlen/Cathy/Emat4680/Squareroot.htm 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.
