Yeah, you gotta be a math geek to like the CORDIC

Well, I shouldn't have made such a generalization. Integer division by powers of two is very fast (if the compiler is designed for such an optimization) because you only need to do a binary right shift to divide a number by two (multiplication works by shifting left). Division of two eighty-bit IEEE floating-point numbers on an eight-bit microcontroller is
very painful.
