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 ...

In this video I will go through my notes to explain how to determine the inverse of a function. We will mainly focus on ...

This short educational script demonstrates how the fast inverse square root algorithm with the magic number 0x5F3759DF can be implemented in Python, and how it can be used to calculate the inverse ...

Abstract: Surface integral equations (SIEs) are widely used for modeling electromagnetic scattering problems. However, after their discretization via the boundary element method (BEM), the spectra and ...

The original Quake III fast inverse square root algorithm used a concept called type punning. The implementation used for type punning in the original algorithm as seen below is considered undefined ...
