A faster version of Quake III's infamous inverse square root algorithm using compiler intrinsic operations. The original Quake III fast inverse square root algorithm used a concept called type punning ...
Abstract: This paper deals with the computation of reciprocals, square roots, inverse square roots, and some elementary functions using small tables, small multipliers, and, for some functions, a ...
Abstract: On the basis of different error functions, a series of continuous-time Zhang dynamics (CTZD) models have been studied for time-varying inverse square root ...
