WebJul 22, 2024 · If you care about maximum precision, note that the integer square root of a 64-bit integer only has 32 significant bits. But for fixed-point, the square roots of numbers between 0.5 and 1.0 are between .75 and 1.0, so you're only losing 1 bit of precision (MSB always set in the result). So the rescaling makes it different from pure integer sqrt ...
