Elementary function calls are a common feature in numerical programs. While their implementations in mathematical libraries are highly optimized, function evaluation is nonetheless very expensive compared to plain arithmetic. Full accuracy is, however, not always needed. Unlike arithmetic, where the performance difference between for example single and double precision floating-point arithmetic is relatively small, elementary function calls provide a much richer tradeoff space between accuracydoi:10.1007/978-3-030-25543-5_11 fatcat:6qhrhilwlvdhlckteoscor455q
