When the loop terminates, we would like to have narrowed down the difference
between pos and neg to 1e-5 or less. (That way, if we report their
average as the result, the comment for bisection will be satisfied.)
One way to ensure that a condition will be true when a loop terminates is to
make the opposite of that condition control the loop.
