Actually I need to specify - I really used (1/2), not (0.5). I'm not
sure how that got in the code I posted...
But this would mean that the (1/2) is being converted to an Int -
which would be 0. anything ^ 0 = 1, and 1+1 = 2. So there, I know
why it is happening.
But how else can I compute a square root?
