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 ... WebMar 1, 2014 · Fixmath is a library of fixed-point math operations and functions. It is designed to be portable, flexible and fast on platforms without floating-point support: The library is written in ANSI-C (C89). The library is thread-safe. There is no hard-coded fixed-point format. The user can set the binary point freely on a per-operation basis.
