Modified Fast Inverse Square Root and Square Root Approximation Algorithms: The Method of Switching Magic Constants

Many low-cost platforms that support floating-point arithmetic, such as microcontrollers and field-programmable gate arrays, do not include fast hardware or software methods for calculating the square root and/or reciprocal square root. Typically, such functions are implemented using direct lookup t...
