WebYes, it once was, but nowadays, compilers are smart enough to optimize all those things for you, so you should not care about this anymore. And about bit-shifting, it once was faster to shift << 2 than to multiply by 4, but those days are over as most processors can multiply in one clock cycle, just like a shift operation. WebOn currently available processors, a bit-wise shift instruction is faster than a multiply instruction and can be used to multiply (shift left) and divide (shift right) by powers of …

Newton-Raphson requires division (integer or float). If you are synthesizing hardware, you can use a table lookup for the highest 10 bits or so, and then continue with either bisection or Newton-Raphson method. brighton v grimsby bbc
