WebDec 10, 2024 · Essentially, yes, because you can specify that your fixed point numbers are 32 or 64 bits, and they will be on all systems. 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. WebThe fixed-point library enables fast real-number operations, especially on CPU's without FPU. This library supports the following functions for fixed-point type with 16, 24, or 29 fraction bits. 1. Multiplication and division 2. Mathematical functions (sin, cos, atan, and sqrt) 3.

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 ... WebApr 29, 2024 · (Note that when I answered this question, it was tagged with C++. The basic techniques still work for C but the library solution does not.)
