快速求平方根
Abstract. Computing reciprocal square roots is necessary in many
applications, such as vector normalization in video games. Often,
some loss of precision is acceptable for a large increase in speed.
This note examines and improves a fast method found in source-
code for several online libraries, and provides the ideas to derive
similar methods for other functions.1
