Floating point numbers may be 32 or 64-bit, but the hardware may actually use 48 or 96 bits to do the calculation and convert to 32 or 64 bits at the end resulting in differences between different types of hardware. 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 ... biological sciences 6th edition
