09.3 Exact vs Approximate Computation
9.3 Exact vs Approximate Computation Not all computations are the same. Some problems ask for an exact answer, while others accept an approximation. Understanding the difference is important, because it affects how we design algorithms and how we interpret results. Exact computation An exact computation produces a result with no error. The answer is precise and fully correct within the rules of mathematics. For example, adding two integers is exact:...
