WebJun 5, 2024 · The task is to create a new version that tracks the difference of each guess to know when to stop. Step 1: Comparing Floats A key piece of the implementation will be knowing when to stop. If the function can't improve the guess, that will be the closest approximation of the square root we can calculate.
