Almost right

Most people want computers to be faster and more accurate. However a group at Purdue University are working on developing computers aimed at ‘approximate computing’. Most computers are designed to compute precise results even when it is not necessary. Approximate computing encompasses using computers to perform calculations good enough for certain tasks that don't require perfect accuracy, potentially doubling efficiency and reducing energy consumption. Approximate computing could endow computers with a capability similar to the human brain's ability to scale the degree of accuracy needed for a given task.
