This is a program I wrote that does the actual square root algorithm that your calculator does. Even though your calculator already has a square root function, I figured it might be neat to write one myself, and spread it around. It performs a total of 40 iterations to gauruntee any square root. Take a look at the code to see how the calculator does it. It's pretty cool.
