Parameters for Simple Iteration
When solving calculations through simple iteration, the iteration process itself must be defined. These parameters are:
Upper Limit. The maximum acceptable result.
Lower Limit. The minimum acceptable result.
Precision. The acceptable difference.
Iterations. The maximum number of loops through the calculation.
Guess. The starting value used in the first iteration.
These inputs become very important when trying to solve a calculation quickly. In the above example, if you had defined an upper limit of 4 and lower limit of 2 you would have determined the result using fewer iterations. An initial guess of 3 would have solved the calculation in a single iteration; and stopping after the third iteration would return a result of –2, which is incorrect.
