Hi Bruce and Evan,

>So, how many iterations does yours take to get SQRT(2) accurate to 15 digits? :) Newton's only took about 8 or 9, I think.

Is mine a bad example because it doesn't reiterate or anything? It just runs once until you are just short of or hit the squareroot depending on the decimal places you pass it. Way different then you two's. Mine probably slower as well. I'll test it.
